This looks like https://issues.apache.org/jira/browse/HBASE-1925. A storefile in the problematic region is missing its sequenceid. Try and figure it (see the issue for clues). There is also the hfile tool for examing metainfo in storefiles:
./bin/hbase org.apache.hadoop.hbase.io.hfile.HFile Do the above for usage. Move aside the bad storefile in hdfs (./bin/hadoop fs -mv SRC TGT). Region should deploy then. Thereafter, please update your hbase so you get the fix that makes it so this doesn't happen in future.
