I have reinstalled Hadoop using Ambari on Hortonworks.
All my services started successfully.
somehow Hadoop fs -ls command is giving following error. can some one help me on this?
# hadoop fs -ls /
/usr/hdp/220.127.116.11-292//hadoop/bin/hadoop.distro: line 31: /usr/hdp/18.104.22.168-40/hadoop/libexec/hadoop-config.sh: No such file or directory
/usr/hdp/22.214.171.124-292//hadoop/bin/hadoop.distro: line 180: exec: : not found
Looks like the executable files are missing. You can try doing the below steps.
1. Re-Install the clients
yum reinstall -y hadoop*
2. Refresh Client configs
Login to Ambari -> Hosts -> Select host where it is failing -> Refresh client configs
If this works please take a moment to login and "Accept" the answer 🙂
If I reinstall will it affect any ambari related services?
any dependency files may be deleted?
please provide me all steps of reinstallation so that it wont get affect any dependency files.
