Hi,

You are definitely experiencing performance degradation cussed by major
compaction. How big is your write load ? Maybe you should consider to
decrease time interval between major compactions if you are writing a lot
data to cluster. Also here is part of hbase book which explains how to
configure major compaction related parameters:
