Hi,
"mycluster' is not a server name, it is the "dfs.nameservices"
my hdfs-site.xml
==============
<property>
<name>dfs.nameservices</name>
<value>mycluster</value>
<final>true</final>
</property>
================
On the other hand, I added an extra entry to hosts, ping mycluster
ping edhcluster
64 bytes from xxx.xxx.xxx: icmp_seq=1 ttl=64 time=0.008 ms
64 bytes from xxx.xxx.xxx: icmp_seq=2 ttl=64 time=0.023 ms
Finally, I tried again from Drill, still the same issue:
Query Failed: An Error Occurred
org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR:
java.net.UnknownHostException: mycluster
It seems that Drill does not support High Available (HA) Hadoop .
Please help.
