ASF GitHub Bot commented on FLINK-8012: --------------------------------------- GitHub user fhueske opened a pull request: https://github.com/apache/flink/pull/4974 [FLINK-8012] [table] Fix TableSink config for tables with time attributes. ## What is the purpose of the change Fix the configuration of TableSinks for Tables with time attributes (`TimeIndicatorTypeInfo`). Time indicators types are internal and must not be exposed to the outside (such as TableSinks). ## Brief change log * the field type of time attributes (rowtime or proctime) is changed to their publicly visible type `SQL_TIMESTAMP`. * an existing test is adapted to check this case. ## Verifying this change * an existing test method in `TableSinkITCase` was adapted. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): **no** - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: **no** - The serializers: **no** - The runtime per-record code paths (performance sensitive): **no** - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: **no** - The S3 file system connector: **no** ## Documentation - Does this pull request introduce a new feature? **no** - If yes, how is the feature documented? **n/a** You can merge this pull request into a Git repository by running: $ git pull https://github.com/fhueske/flink tableSinkConfig Alternatively you can review and apply these changes as the patch at: https://github.com/apache/flink/pull/4974.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #4974 ---- commit ab8120da2e7f751da2b5760e5b17d76264dcfcab Author: Fabian Hueske <fhue...@apache.org> Date: 2017-11-07T16:57:39Z [FLINK-8012] [table] Fix TableSink config for tables with time attributes. ---- > Table with time attribute cannot be written to CsvTableSink > ----------------------------------------------------------- > > Key: FLINK-8012 > URL: https://issues.apache.org/jira/browse/FLINK-8012 > Project: Flink > Issue Type: Bug > Components: Table API & SQL > Affects Versions: 1.4.0, 1.3.2 > Reporter: Fabian Hueske > Assignee: Fabian Hueske > Priority: Critical > Fix For: 1.4.0, 1.3.3 > > > A Table with a time attribute ({{TimeIndicatorTypeInfo}}) cannot be written > to a {{CsvTableSink}}. > Trying to do so results in the following exception: > {code} > Exception in thread "main" org.apache.flink.table.api.TableException: The > time indicator type is an internal type only. > at > org.apache.flink.table.api.TableEnvironment.org$apache$flink$table$api$TableEnvironment$$validateFieldType$1(TableEnvironment.scala:937) > at > org.apache.flink.table.api.TableEnvironment$$anonfun$generateRowConverterFunction$2.apply(TableEnvironment.scala:963) > at > org.apache.flink.table.api.TableEnvironment$$anonfun$generateRowConverterFunction$2.apply(TableEnvironment.scala:960) > at > scala.collection.mutable.ResizableArray$class.foreach(ResizableArray.scala:59) > at scala.collection.mutable.ArrayBuffer.foreach(ArrayBuffer.scala:48) > at > org.apache.flink.table.api.TableEnvironment.generateRowConverterFunction(TableEnvironment.scala:960) > at > org.apache.flink.table.api.StreamTableEnvironment.getConversionMapper(StreamTableEnvironment.scala:289) > at > org.apache.flink.table.api.StreamTableEnvironment.translate(StreamTableEnvironment.scala:810) > at > org.apache.flink.table.api.StreamTableEnvironment.writeToSink(StreamTableEnvironment.scala:263) > at org.apache.flink.table.api.Table.writeToSink(table.scala:857) > at org.apache.flink.table.api.Table.writeToSink(table.scala:830) > {code} > The time attribute should be automatically converted into a {{SQL_TIMESTAMP}} > type. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
