---------------------------------
Summary: "mutateRow" maybe fail when Region Server restarted(or
killed) or Region Balance
Key: HBASE-10803
URL: https://issues.apache.org/jira/browse/HBASE-10803
Project: HBase
Issue Type: Bug
Affects Versions: 0.96.1.1
Environment: hbase0.96.1.1
hadoop2.2
jdk1.7
5 Region Server
Reporter: LiJianyin
found that the operation "mutateRow" maybe fail if Region Server restarted(or
killed) or Region Balance, but the java client didnot throw exceptions and
there was no exception in the server's log either.
the client code :
HTableInterface table = connection.getTable(TABLE_NAME);
Delete d = new Delete(Bytes.toBytes(rowkey), time);
d.deleteColumns(FAMILY, Bytes.toBytes(id), time);
Put p = new Put(Bytes.toBytes(rowkey));
p.add(FAMILY_DEL, Bytes.toBytes(id), time,
Bytes.toBytes(value));
RowMutations rm = new
RowMutations(Bytes.toBytes(rowkey));
rm.add(d);
rm.add(p);
table.mutateRow(rm);
table.close();
the test data:
Operator Type: put; mutateRow(delete+put)
Operator Total Count:202194822 put:160866148 mutateRow:41328674
All put correct, but 161 mutateRow incorrect (161 data was not
mutateRowed in fact).
then we checked log when the time mutateRow failed, NO EXCEPTION
THROWED, found that as follow:
39 failed hbase auto region-balance
44 failed hbase region server killed
59 failed hbase region server restart
19 failed hadoop datanode restart
