ASF subversion and git services commented on NIFI-3678:
-------------------------------------------------------
Commit 292dd1d66b1726794f0d34523578727ea3a7fe08 in nifi's branch
refs/heads/master from [~markap14]
[ https://git-wip-us.apache.org/repos/asf?p=nifi.git;h=292dd1d ]
NIFI-3678: Ensure that we catch EOFException when reading header information
from WAL Partition files; previously, we caught EOFExceptions when reading a
'record' from the WAL but not when reading header info
NIFI-3678: If we have a transaction ID but then have no more data written to
Partition file, we end up with a NPE. Added logic to avoid this and instead
return null for the next record when this happens
This closes #1656.
