Chia-Ping Tsai commented on HBASE-20231:
----------------------------------------
The condition is used to avoid empty qualifier? If so, using
"getQualifierLength != 0" is more better. Otherwise LGTM
{code:java}
+ if (Bytes.compareTo(CellUtil.cloneQualifier((KeyValue) o),
+ HConstants.EMPTY_BYTE_ARRAY) != 0) {{code}
> Not able to delete column family from a row using RemoteHTable

> Key: HBASE-20231
> URL: https://issues.apache.org/jira/browse/HBASE-20231
> Project: HBase
> Issue Type: Bug
> Components: REST
> Reporter: Pankaj Kumar
> Assignee: Pankaj Kumar
> Priority: Major
> Fix For: 1.5.0
>
> Attachments: HBASE-20231-branch-1.patch, HBASE-20231.patch

> Example code to reproduce the issue,
> {code:java}
> Cluster cluster = new Cluster();
> cluster.add("rest-server-IP", rest-server-port);
> Client client = new Client(cluster);
> RemoteHTable table = new RemoteHTable(client, "t1");
> // Insert few records,
> Put put = new Put(Bytes.toBytes("r1"));
> put.add(Bytes.toBytes("cf1"), Bytes.toBytes("c1"), Bytes.toBytes("c1"));
> put.add(Bytes.toBytes("cf1"), Bytes.toBytes("c2"), Bytes.toBytes("c2"));
> put.add(Bytes.toBytes("cf2"), Bytes.toBytes("c1"), Bytes.toBytes("c1"));
> table.put(put);
> put = new Put(Bytes.toBytes("r2"));
> put.add(Bytes.toBytes("cf1"), Bytes.toBytes("c1"), Bytes.toBytes("c1"));
> put.add(Bytes.toBytes("cf1"), Bytes.toBytes("c2"), Bytes.toBytes("c2"));
> put.add(Bytes.toBytes("cf2"), Bytes.toBytes("c1"), Bytes.toBytes("c1"));
> table.put(put);
> // Delete the entire column family from the row
> Delete del = new Delete(Bytes.toBytes("r2"));
> del.addFamily(Bytes.toBytes("cf1"));
> table.delete(del);
> {code}
> Here the problem is in building row specification in
> RemoteHTable.buildRowSpec(). Row specification is framed as "/t1/r2/cf1:"
> instead of "/t1/r2/cf1".
