Manno15 opened a new pull request #2181:
URL: https://github.com/apache/accumulo/pull/2181
Fixes #2172.
I wanted to get my progress on this issue out there as things are close to
being finished. I still need to do more testing against the old-style WAL and
to do more code clean-up. Especially in `RecoveryLogIterator` as there is some
repeated code and I am not quite sure what is needed for the single file case.
Beyond that, everything seems to be working as expected when using wal-info.
Sample below of the output with wal-info, there appears to be a memory issue
that I am taking a look at now.
