------------------------------
Summary: Replication Resiliency: for listing files for a partition
/ table
Key: HIVE-19188
URL: https://issues.apache.org/jira/browse/HIVE-19188
Project: Hive
Issue Type: Bug
Reporter: anishek
When for listing files for a partition / table fails during dump we should
have ability to *retry with wait,* so the whole dump process does not fail.
additionally the filesystem object used to list the files might have to be
recreated since only IOException is thrown by the object for various operations
and we dont know if the internal DFSClient it holds has a broken connection due
to network error. This has to be done using Filesystem.newInstance() since
caching of fs object might be enabled.
currently caching of the filesystem object is depended upon
* Scheme
* Authority
* UGI
* And a long called unique defaults to 0 unless explicitly provided, which is
never the case from Hive since we call default constructor which uses 0L by
default internally.
