All, With 0.98.12 on top of Hadoop 2.6.0, running:
./bin/hdfs fsck -openforwrite Reports that the WALs are corrupt. Without -openforwrite, everything is fine. They all seem to be "MISSING 1 blocks of total size 83 B" for each region server WAL. May be the same as to https://issues.apache.org/jira/browse/HDFS-8809 (using hbase 1.1.1 there), but in our case, only -openforwrite is affected. There don't seem to be any issues resulting from this afaict. Anyone else run into this? Thanks, James
