Exporting across versions was why I tried webhdfs. I have a cluster =
running HBase 0.94 and wanted to export a=20
table to a different cluster running HBase 0.96. I got the export to =
work, but attempting to
do a restore_snapshot results in:

    TableInfoMissingException: No table descriptor file

so I assume snapshot are not compatible between versions. Is there any =
way to copy the
table from the old cluster to the new one?=20
