Hi,
I'm running hbase 0.98.1
When using TableMapReduceUtil to init a MR job on a snapshot, I got an
error :
org.apache.hadoop.hbase.TableInfoMissingException: No table descriptor file
under hdfs://hbase/hbase/.hbase-snapshot/xxx-snapshot
at
Hi, anybody knows why I can't skip flush when taking snapshot ?
snapshot 'aaa', 'aaa_snapshot', {SKIP_FLUSH = true}
NameError: uninitialized constant SKIP_FLUSH
without {SKIP_FLUSH = true}, the command works fine/
Regards,
Guangle

Please take a look at:
HBASE-9360 Enable 0.94 - 0.96 replication to minimize upgrade down time

Hi, Ted you are right, hfiles on 0.94 cluster are v2 by default. I
actually don't need the convert tool.
To migrate that data to another 0.96 cluster, does it work by copying
over
hfiles ? How to handle the meta data of the table
Hi, All
I have hfiles in HBase 9.4 cluster that I want to migrate to HBase 9.6
cluster.
What's the proper process to handle this ?

on upgrades. Also,
please consider upgrading to 0.98. The 0.96 line is in minimum maintenance
mode and 0.98 is considered the stable/production line.

Hi, All
I
perform major compaction after which your HFiles
would be converted to HFileV2.

For some reason, I can't do a in-place upgrading for the cluster. Is
there
a tool there I can use to convert hfileV1
being 1 ?

Ted Thanks for your answer!
Actually that wouldn't convert automatically. The problem is 0.94 is
using
hfileV1, and that is online cluster that I can't shut down and do hbase
upgrade/check file
