Andrew Wong updated HUDI-628:
-----------------------------
Summary: MultiPartKeysValueExtractor does not work with run_sync_tool.sh
(was: MultiPartKeysValueExtractor does not work with
HoodieHiveClient.getPartitionClause)
> MultiPartKeysValueExtractor does not work with run_sync_tool.sh
> ---------------------------------------------------------------
>
> Key: HUDI-628
> URL: https://issues.apache.org/jira/browse/HUDI-628
> Project: Apache Hudi (incubating)
> Issue Type: Bug
> Reporter: Andrew Wong
> Priority: Major
> Attachments: stack_trace.txt
>
>
> The [https://hudi.apache.org/docs/quick-start-guide.html] example data has a
> column `partitionpath` which holds values like `americas/brazil/sao_paulo`.
> Using the docker environment, you can change the basePath from the quickstart
> to save to hdfs://user/hive/warehouse/hudi_trips_cow. Then you can see the
> folder in the HDFS browser, similar to the stock_ticks_cow folder created in
> the docker demo.
> However, if you try to use run_sync_tool.sh to sync the table to Hive, you
> get the error: "java.lang.IllegalArgumentException: Partition key parts
> [partitionpath] does not match with partition values [americas, brazil,
> sao_paulo]. Check partition strategy. "
> {quote}{{/var/hoodie/ws/hudi-hive/run_sync_tool.sh --jdbc-url
> jdbc:hive2://hiveserver:10000 --user hive --pass hive --partitioned-by
> partitionpath --partition-value-extractor
> org.apache.hudi.hive.MultiPartKeysValueExtractor -MultiPartKeysValueExtractor
> -base-path /user/hive/warehouse/hudi_trips_cow --database default --table
> hudi_trips_cow}}
> {quote}
> This error is thrown in `HoodieHiveClient.getPartitionClause`, which uses
> `extractPartitionValuesInPath` to get a list of partitionValues. The problem
> is that it compares the length of the partitionValues to the length of the
> partitionField. In this example, there is only 1 partitionField,
> "partitionpath," which is split into 3 partitionValues. Thus the check fails
> and throws the exception.
