When you run OfflineMetaRepair, most likely you will run it from your userid or root.  Then we may get some opaque errors like "java.lang.AbstractMethodError: org.apache.hadoop.hbase.ipc.RpcScheduler.getWriteQueueLength()".    If you check in HDFS, you may see that the meta directory is no longer owned by hbase:   $ hdfs dfs -ls /hbase/data/hbase/ Found 2 items drwxr-xr-x - root hbase 0 2017-09-12 13:58 /hbase/data/hbase/meta drwxr-xr-x - hbase hbase 0 2016-06-15 15:02 /hbase/data/hbase/namespace Manually chown -R it and restart HBase fixed it for me.     ...
