Did you look at your GC logs? Probably the compaction process is running your region server
out of memory. Can you provide more details on your setup? Max heap size? Max Region HFile

Subject: RegionServer crash without any errors (compaction?)


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,<
2013-11-07 15:29:10,471 INFO
org.apache.hadoop.hbase.regionserver.StoreFile: Delete Family Bloom filter
type for hdfs://
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

best regards
