Issues on disabling compaction in HBase 0.94.2

Hi, I want to disable automatic compaction in HBase. Currently I used
following configurations in conf/hbase-site.xml
The problem is compaction does not really be disable. As write are issued
into HBase, it can be observed when there is a
flush to HFile, it will trigger a compaction. Do I miss anything from
following xml configurables.
Regards,
Yun

Hi, I have figured out the problem... The XML snippet in previous email works for HBase 092 but not for 094. By consulting HBase-default.xml, it can be done to disable all compact ions. Thanks all the same.

Yun

Hi Yun,

Are you trying to disable Minor compactions?
