stack commented on HBASE-15536:
-------------------------------
TestWALOpenAfterDNRollingStart seems to be only legit failure.
WALFactory#createReader at line #300 keeps catching below exception then
retrying.
Cannot obtain block length for
LocatedBlock{BP-564709508-192.168.1.139-1513103544167:blk_1073741830_1006;
getBlockSize()=0; corrupt=false; offset=0;
