Subject HBase Import Error
Date Sat, 29 Aug 2015 14:31:55 GMT
I was able to successfully export data to S3 using below command.

hbase org.apache.hadoop.hbase.mapreduce.Export docs
s3n://KEY:ACCESSKEY@fdocshbase/data/bkp1 1440760612 1440848237

and I was able to import data to a new table (after creation) with command

hbase org.apache.hadoop.hbase.mapreduce.Import docsnew
s3n://KEY:ACCESSKEY@fdocshbase/data/bkp1

I exported with different time ranges to other directories like bkp2 bkp3.

When I was trying to import all directories into Hbase, getting a
filenotfound exception.

[hdfs@ip-172-31-59-10 ~]$ hbase org.apache.hadoop.hbase.mapreduce.Import
docsnew s3n://KEY:ACCESSKEY@fdocshbase

Its looking for data directory always?   I did export data to HDFS as
well.  Had a similar issue in HDFS as well.  I created bakcup directory
like /fdocshbase/bkp1, /fdocshbase/bkp2 and so on....
This created similar problem above while importing.  But, When I created
directories like /fdocshbase/data/bkp1, /fdocshbase/data/bkp2......and
provide /fdocshbase/data/ as input to import, it works.

But, this is not working on S3. I tried creating directory like
fdocshbase/data/data
 and placed all bkp* directories in it.

Any thoughts?  Any quick resolutions?

Regards,
Arun
