> Project: Hive
> Issue Type: Bug
> Components: HCatalog, Streaming
> Reporter: Shawn Weeks
> Assignee: Ádám Szita
> Priority: Minor
>
> The patch in HIVE-13151 added FileSystem.closeAllForUGI(ugi); to the close
> method of HiveEndPoint for the legacy Streaming API. This seems to have a
> side effect of closing the FileSystem for all open TransactionBatches as used
> by NiFi and Storm when writing to multiple partitions. Setting
> fs.hdfs.impl.disable.cache=true negates the issue but at a performance cost.
