huan created HBASE-21525:
----------------------------
Summary: java.io.IOException: java.lang.ClassNotFoundException:
clone_snapshot from hbase2.0.0 to hbase1.2.0
Key: HBASE-21525
URL: https://issues.apache.org/jira/browse/HBASE-21525
Project: HBase
Issue Type: Bug
Components: snapshots
Affects Versions: 2.0.0, 1.2.0
Reporter: huan
When I use
{code:java}
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot
"wh_scan_issue_monitor_on_snap_1" -copy-from hdfs://xxxx:8020/hbase -copy-to
hdfs://xxx:8020/hbase
{code}
to copy snapshot from hbase2.0.0 to hbase 1.2.0 and then use
{code:java}
clone_snapshot
'wh_scan_issue_monitor_on_snap_1',"wh_scan_issue_monitor_table"{code}
to restore the table;
There are no errors on client and hbase master.
but I can not scan any data in this new table.
So when I search the log in regionserver which that region running on .I find
the below error log
{code:java}
