Hi, I have a cluster with 7 regionserver. Some of them are crashing from time to time wihtout any error message in the hbase log. If I take a look at the log at the time I found this:
2013-11-07 15:29:02,511 INFO org.apache.hadoop.hbase.regionserver.Store: Starting compaction of 2 file(s) in 1 of P_SO,< http://xmlns.com/foaf/0.1/homepage>,1383188177383.59d0259c87c07dc666a5600ba4d6c916. i$ 2013-11-07 15:29:10,471 INFO org.apache.hadoop.hbase.regionserver.StoreFile: Delete Family Bloom filter type for hdfs:// pc08.pool.ifis.uni-luebeck.de:8020/hbase/P_SO/59d0259c87c07dc666a5600ba4d6c916/.tmp/f$ 2013-11-07 15:31:05,944 INFO org.apache.hadoop.hbase.util.VersionInfo: HBase 0.94.6-cdh4.4.0 .... restart At this time 2 of the 7 RS crashed, both has this compaction message before they crashed. I don't know exactly what compaction is, but it seems that this compaction has to do with the crash. What can I do to avoid this restart/crash? best regards
