Vinayakumar B updated HADOOP-11296:
-----------------------------------
Attachment: HADOOP-11296-001.patch
Issue was 'xargs' will consider full line of input as one argument when it
reads from stdin/pipe.
in {{hadoop-functions.sh#hadoop_connect_to_hosts}} {{SLAVE_NAMES}} was space
separated hostnames in one line. So it was considering whole list as one host.
Here is the code snippet.
{code} echo "${SLAVE_NAMES}" | \
xargs -n 1 -P"${HADOOP_SSH_PARALLEL}" \
-I {} bash -c -- "hadoop_actual_ssh {} ${params}"{code}
> hadoop-daemons.sh throws 'host1: bash: host3: command not found...'
