Facing issues with region availability and it seems to be due to compactions. We are getting below exception when we try to access region org.apache.hadoop.hbase.NotServingRegionException: Region is not online But when we checked corresponding region server logs we can see lot of compactions happening on the table. Does table becomes unaccessible during compaction? Is there a way to reduce number of compactions through some setting? ... View more

@Jason Knaster I just tested this scenario on Hbase 1.1.2 and it worked. [root@ey ~]# cat /usr/hdp/current/hbase-master/conf/hbase-site.xml <configuration> <property> <name>hbase.rootdir</name> <value>file:///test/hbase</value> </property> <property> <name>hbase.zookeeper.property.dataDir</name> <value>/test/zookeeper</value> </property> </configuration> root@ey hbase-master]# ./bin/start-hbase.sh [root@ey hbase-master]# hbase shell hbase(main):001:0> create 't1','c1' 0 row(s) in 1.4790 seconds => Hbase::Table - t1 hbase(main):002:0> put 't1','123','c1:id','123m' 0 row(s) in 0.1500 seconds hbase(main):003:0> scan 't1' ROW COLUMN+CELL 123 column=c1:id, timestamp=1464183553280, value=123m 1 row(s) in 0.0340 seconds Then Stopped the standlone Hbase . Compressed and transfer the hbase dir to another node. [root@ey hbase-master]# tar -cvf test.tar /test [root@ey ~]# scp test.tar root@AD:/root/ On Node "AD" [root@AD ~]# tar xvf test.tar [root@AD ~]# mv /root/test / Copied same hbase-site.xml from primary hbase.
