Subject Data migration from hbase 0.90 to hbase 0.98
Date Wed, 17 Sep 2014 12:13:59 GMT
Hello there,

I’m wondering if anyone knows how to move tables in hbase 0.90 to hbase 0.98? I did export
on hbase 0.90 and import to hbase 0.98. However it throws exception like

java.lang.Exception: java.io.IOException: keyvalues=NONE read 2 bytes, should read 143121
	at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:403)

Hope someone can shed some light upon this. Many thanks.
