------------------------------
Summary: repl load does not lead to excessive memory consumption
for multiple functions from same binary jar
Key: HIVE-16897
URL: https://issues.apache.org/jira/browse/HIVE-16897
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Affects Versions: 3.0.0
Reporter: anishek
Assignee: anishek
Fix For: 3.0.0
as part of function replication we currently keep a separate copy of the binary
jar associated with the function ( this should be same on the primary warehouse
also since each hdfs jar location given during creation of function will
download the resource in a separate resource location thus leading to the same
jar being included in class path multiple times)
this will lead to excessive space used to keep all jars in classpath, solve
this by identifying the common binary jar ( using checksum from primary on
replica) and not creating multiple copies thus preventing excessive memory
usage.
