HDFS is so slow as Name server is unreachable

HDFS is so slow as Name server is unreachable

New Contributor

Hi ,

HDFS is so slow as  one of name server in /etc/resolv.conf is unreachable. but why HDFS needs to use DNS ,although /etc/hosts already configured and contains the cluster hostnames.

it takes 20 sec in this step "ipc.Client: getting client out of cache: org.apache.hadoop.ipc.Client@368247b9"

 

could you please help to disable HDFS from using DNS at all and just depends on hosts file?
