Jesse Yates commented on HBASE-10076:
-------------------------------------
bq. Any interest in bringing in the new test TestCellUtil.
testOverlappingKeys() ? Not needed that much, just checking
Done - good call.
bq. Not sure about the change in TableInputFormatBase. Is this needed? Let's
leave this out otherwise.
Not needed, but this is a cleaner, better implementation and good to reuse the
util, now that we have it. Agree its a little extra and a bit unneccessary, but
trivially so.
bq. In the original patch, TableMapReduceUtil. initTableMapperJob() now accepts
an initCredentials param, because we do not want to get tokens from HBase at
all. Otherwise, if hbase is used with security, offline clusters won't work.
Looks like in 0.94 its just added based on the config. In trunk, looks like
TableMapReduceUtil.initTableSnapshotMapperJob just calls initTableMapperJob
without any parameter, which always initializes the credentials. Maybe a bug in
trunk? Seems like you would need a more sweeping change to make it configurable
as well.
