The subject of this thread says '9.4' - I assume you meant '0.94' release.
If so, please make correction in the subject.
Looking at hbase-default.xml from 0.94 branch:
<property>
<name>hfile.format.version</name>
<value>2</value>
<description>
The HFile format version to use for new files. Set this to 1 to
test
backwards-compatibility. The default value of this option should
be
consistent with FixedFileTrailer.MAX_VERSION.
</description>
</property>
Are you running 0.94 cluster with the above config value being 1 ?
Cheers
