Subject No serialized HRegionInfo
Date Fri, 29 May 2015 01:48:01 GMT
Hi,

I kept running into this whenever I remove tables

WARN catalog.MetaReader: No serialized HRegionInfo in
keyvalues={predictionio_eventdata:events_0,,1430338711772.915bc4b384b2fa24cc6113319f830100./info:seqnumDuringOpen/1430338711901/Put/vlen=8/mvcc=0,

create tables

WARN client.HBaseAdmin: No serialized HRegionInfo in

When doing hbck, I found some 1800 inconsistencies of the form

ERROR: Empty REGIONINFO_QUALIFIER found in hbase:meta

  keyvalues={predictionio_eventdata:events_0,,1431758974706.765ee245540bd03dcd1ef66071e301d0./info:seqnumDuringOpen/1431758974883/Put/vlen=8/mvcc=0,
predictionio_eventdata:events_0,,1431758974706.765ee245540bd03dcd1ef66071e301d0./info:server/1431758974883/Put/vlen=46/mvcc=0,
predictionio_eventdata:events_0,,1431758974706.765ee245540bd03dcd1ef66071e301d0./info:serverstartcode/1431758974883/Put/vlen=8/mvcc=0}

while all the tables are okay.

I ran "hbase hbck -fixEmptyMetaCells" according to the suggestion on
http://mail-archives.apache.org/mod_mbox/hbase-dev/201312.mbox/%3CCAPQV63VrpJ-_ffOo92m=RyaZa+Z3LrpPhiNMi5Szx5uar=u0rw@mail.gmail.com%3E
which
cleared the inconsistencies and those warning messages, but the "No
serialized HRegionInfo" and HBase inconsistencies continued to accumulate
so some config is still not quite right. Any help is appreciated.

Tom
