--------------------------------

Hi Neeraja,

I tried but still got the same error from drill log.
drill-env.sh:
{code}
export HADOOP_HOME=/opt/cloudera/parcels/CDH-5.1.0-1.cdh5.1.0.p0.53/lib/hadoop
export CLASSPATH=/opt/cloudera/parcels/CDH/lib/hadoop/hadoop-annotations.jar:/opt/cloudera/parcels/CDH/lib/hadoop/hadoop-auth.jar:/opt/cloudera/parcels/CDH/lib/hadoop/hadoop-common.jar:/opt/cloudera/parcels/CDH/lib/hadoop-hdfs/hadoop-hdfs.jar:/opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-client-core.jar:$CLASSPATH
{code}


drill-override.conf:
{code}
drill.exec: {
  cluster-id: "mydrill",
  zk.connect: "admin.xxx.com:2181,hdw1.xxx.com:2181,hdw3.xxx.com:2181"
}
{code}

Any suggestions on this?

Thanks,
Hao

> On my cluster, I am using CDH5 hdfs, and it all client configurations are valid. For
example, on the drillbit server:
> {code}
> [root@hdm ~]# hdfs dfs -ls /
> Found 3 items
> drwxr-xr-x   - hbase hbase               0 2014-08-04 22:55 /hbase
> drwxrwxrwt   - hdfs  supergroup          0 2014-07-31 16:31 /tmp
> drwxr-xr-x   - hdfs  supergroup          0 2014-07-11 12:06 /user
> {code}
> Is there anything wrong with the storage plugin syntax for HDFS?
> If so, can drill log prints more debug info to show the reason why it failed?
> Thanks.
