Subject High iowait in idle hbase cluster
Date Wed, 02 Sep 2015 16:11:55 GMT
I’m having strange behaviour in hbase cluster. It is almost idle, only <5 puts and gets.

But the data in hdfs is increasing, and region servers have very high iowait(>100, in 2
core CPU).
iotop shows that datanode process is reading and writing all the time.
Any suggestions?
