> 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.
