Use only LogDocMergePolicy while fixing LogByteSizeMergePolicy
CI builds are timing out after running for an hour. I have tracked down the
issue to the use of LogByteSizeMergePolicy for merges. Lucene tests randomly
select merge policy from the two choices, one of them being LogByteSize. There
are two conditions necessary for the issue to be triggered:
- LogByteSizeMergePolicy needs to be selected by random switches
- mergePolicy.NoCFSRatio needs to be set to something between 0.0 and 1.0
When these two conditions are true, segment merge keeps on running merges
over and over and over again until out of memory is reached or segments to be
merged list is greater than max long.
While I check on the issue with this merge policy, we can disable it from
being used so that the rest of the PRs can be pulled in and immediate feedback
from CI received.
