> Creating new tables/partitions may fail with an AlreadyExistsException if there is an
error part way through the creation and the HMS tries again without properly cleaning up or
checking if this is a retry.
> While partitioning a new table via a script on distributed hive (MetaStore on the same
machine) there was a long timeout and then:
> {code}
> FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. AlreadyExistsException(message:Partition
already exists:Partition( ...
> {code}
> I am assuming this is due to retry. Perhaps already-exists on retry could be handled
better.
> A similar error occurred while creating a table through Impala, which issued a single
createTable call that failed with an AlreadyExistsException. See the logs related to table
tmp_proc_8_d2b7b0f133be455ca95615818b8a5879_7 in the attached hive-snippet.log
