Error conditions in Databricks
This is a list of common, named error conditions returned by Databricks.
Databricks Runtime and Databricks SQL
ARITHMETIC_OVERFLOW
<message>.<alternative> If necessary set <config> to “false” (except for ANSI interval type) to bypass this error.
CANNOT_CHANGE_DECIMAL_PRECISION
<value> cannot be represented as Decimal(<precision>, <scale>). If necessary set <config> to “false” to bypass this error.
CANNOT_DROP_AMBIGUOUS_CONSTRAINT
Cannot drop the constraint with the name <constraintName> shared by a CHECK constraint
and a PRIMARY KEY or FOREIGN KEY constraint. You can drop the PRIMARY KEY or
FOREIGN KEY constraint by queries:
ALTER TABLE .. DROP PRIMARY KEY or
ALTER TABLE .. DROP FOREIGN KEY ..
CANNOT_READ_SENSITIVE_KEY_FROM_SECURE_PROVIDER
Cannot read sensitive key ‘<key>’ from secure provider
CAST_INVALID_INPUT
The value <value> of the type <sourceType> cannot be cast to <targetType> because it is malformed. Correct the value as per the syntax, or change its target type. Use try_cast to tolerate malformed input and return NULL instead. If necessary set <config> to “false” to bypass this error.
CAST_OVERFLOW
The value <value> of the type <sourceType> cannot be cast to <targetType> due to an overflow. Use try_cast to tolerate overflow and return NULL instead. If necessary set <config> to “false” to bypass this error.

MISSING_COLUMN
Column ‘<columnName>’ does not exist. Did you mean one of the following? [<proposal>]
MULTIPLE_LOAD_PATH
Databricks Delta does not support multiple input paths in the load() API.
paths: <pathList>. To build a single DataFrame by loading
multiple paths from the same Delta table, please load the root path of
the Delta table with the corresponding partition filters. If the multiple paths
are from different Delta tables, please use Dataset’s union()/unionByName() APIs
to combine the DataFrames generated by separate load() API calls.
NOT_A_TABLE_FUNCTION
<functionName> is not a table function. Please check the function usage: DESCRIBE FUNCTION <functionName>
NOT_A_VALID_DEFAULT_EXPRESSION

RESERVED_CDC_COLUMNS_ON_WRITE
The write contains reserved columns <columnList> that are used
internally as metadata for Change Data Feed. To write to the table either rename/drop
these columns or disable Change Data Feed on the table by setting
<config> to false.
SECOND_FUNCTION_ARGUMENT_NOT_INTEGER
The second argument of ‘<functionName>’ function needs to be an integer.
UNRESOLVED_MAP_KEY
Cannot resolve column <columnName> as a map key. If the key is a string literal, please add single quotes around it. Otherwise, did you mean one of the following column(s)? [<proposal>]
UNSUPPORTED_CONSTRAINT_TYPE

UNSUPPORTED_DESERIALIZER
The deserializer is not supported:
For more details see UNSUPPORTED_DESERIALIZER
UNSUPPORTED_GROUPING_EXPRESSION

UNSUPPORTED_SAVE_MODE
The save mode <saveMode> is not supported for:
For more details see UNSUPPORTED_SAVE_MODE
UNTYPED_SCALA_UDF
You’re using untyped Scala UDF, which does not have the input type information. Spark may blindly pass null to the Scala closure with primitive-type argument, and the closure will see the default value of the Java type for the null argument, e.g. udf((x: Int) => x, IntegerType), the result is 0 for null input. To get rid of this error, you could:
use typed Scala UDF APIs(without return type parameter), e.g.
udf((x: Int) => x)use Java UDF APIs, e.g.
udf(new UDF1[String, Integer] { override def call(s: String): Integer = s.length() }, IntegerType), if input types are all non primitiveset “spark.sql.legacy.allowUntypedScalaUDF” to “true” and use this API with caution

Expect a full scan of the latest version of the Delta source, but found a historical scan of version <historicalVersion>
DELTA_FAIL_RELATIVIZE_PATH
Failed to relativize the path (<path>). This can happen when absolute paths make
it into the transaction log, which start with the scheme
s3://, wasbs:// or adls://. This is a bug that has existed before DBR 5.0.
To fix this issue, please upgrade your writer jobs to DBR 5.0 and please run:
%%scala com.databricks.delta.Delta.fixAbsolutePathsInLog(“<path>”).
If this table was created with a shallow clone across file systems
(different buckets/containers) and this table is NOT USED IN PRODUCTION, you can
set the SQL configuration spark.databricks.delta.vacuum.relativize.ignoreError
to true. Using this SQL configuration could lead to accidental data loss,
therefore we do not recommend the use of this flag unless
this is a shallow clone for testing purposes.
DELTA_FILE_TO_OVERWRITE_NOT_FOUND
File (<path>) to be rewritten not found among candidate files:
<pathList>
DELTA_FOUND_MAP_TYPE_COLUMN

DELTA_INCORRECT_ARRAY_ACCESS_BY_NAME
An ArrayType was found. In order to access elements of an ArrayType, specify
<rightName>
Instead of <wrongName>
DELTA_INCORRECT_LOG_STORE_IMPLEMENTATION
The error typically occurs when the default LogStore implementation, that
is, HDFSLogStore, is used to write into a Delta table on a non-HDFS storage system.
In order to get the transactional ACID guarantees on table updates, you have to use the
correct implementation of LogStore that is appropriate for your storage system.
See <docLink> for details.
DELTA_INDEX_LARGER_OR_EQUAL_THAN_STRUCT
Index <position> to drop column equals to or is larger than struct length: <length>
DELTA_INDEX_LARGER_THAN_STRUCT
Index <index> to add column <columnName> is larger than struct length: <length>

Couldn’t find Metadata while committing the first version of the Delta table. To disable
this check set <deltaCommitValidationEnabled> to “false”
DELTA_MISSING_CHANGE_DATA
Error getting change data for range [<startVersion> , <endVersion>] as change data was not
recorded for version [<version>]. If you’ve enabled change data feed on this table,
use DESCRIBE HISTORY to see when it was first enabled.
Otherwise, to start recording change data, use `ALTER TABLE table_name SET TBLPROPERTIES
(<key>=true)`.
DELTA_MISSING_FILES_UNEXPECTED_VERSION
The stream from your Delta table was expecting process data from version <startVersion>,
but the earliest available version in the deltalog directory is <earliestVersion>. The files
in the transaction log may have been deleted due to log cleanup. In order to avoid losing
data, we recommend that you restart your stream with a new checkpoint location and to
increase your delta.logRetentionDuration setting, if you have explicitly set it below 30
days.
If you would like to ignore the missed data and continue your stream from where it left
off, you can set the .option(“<option>”, “false”) as part
of your readStream statement.

DELTA_MULTIPLE_CONF_FOR_SINGLE_COLUMN_IN_BLOOM_FILTER
Multiple bloom filter index configurations passed to command for column: <columnName>
DELTA_MULTIPLE_SOURCE_ROW_MATCHING_TARGET_ROW_IN_MERGE
Cannot perform Merge as multiple source rows matched and attempted to modify the same
target row in the Delta table in possibly conflicting ways. By SQL semantics of Merge,
when multiple source rows match on the same target row, the result may be ambiguous
as it is unclear which source row should be used to update or delete the matching
target row. You can preprocess the source table to eliminate the possibility of
multiple matches. Please refer to
<usageReference>
DELTA_NAME_CONFLICT_IN_BUCKETED_TABLE
The following column name(s) are reserved for Delta bucketed table internal usage only: <names>
DELTA_NEW_CHECK_CONSTRAINT_VIOLATION
