Hi, Thanks for the resolution. Is there any specific procedures to upgrade krb packages to 1.15.1-19?.. Detailed steps to upgrade and post upgrade to start hadoop cluster would be more helpful

@Jay Kumar SenSharma It tried adding "ambari." to query and it works. ambari=# update ambari.repo_version set stack_id = (select stack_id from ambari.stack where stack_version = '2.3') where display_name like 'BigInsights%'; UPDATE 1 ambari=#

Hi, In order to find the adequate space in any directory during installation or upgrade procedures, for example while doing HDP upgrade you should verify about the availability of adequate space on /usr/hdp for the target HDP version. For that use below format: df -h <Path_of_interest> Example : [alex@machine1]# df -h /usr/hdp/ Filesystem Size Used Avail Use% Mounted on /dev/mapper/system-root 528G 22G 506G 5% / [alex@machine1]# You can all parameters like Size of disk, used space, available spave and percentage of usage.

@Aditya : Thank, this is really informative

Back up all the data that resides under <File_system_mount point>/apps/accumulo/data directory. Remove the <File_system_mount point>/apps/accumulo/data directory by running sudo -u hdfs hdfs dfs -rm -R /apps/accumulo/data Reinitialize the Accumulo service, run sudo -u accumulo ACCUMULO_CONF_DIR=/etc/accumulo/conf/server accumulo init --instance-name hdp-accumulo-instance --clear-instance-name. Enter a valid password when asked for initial password for root. Update the Accumulo root password and trace user password from the Ambari GUI. Set it to the same password as provided in the previous step. Restart Accumulo. After the Accumulo service gets started successfully and the service check passes, you can restore the data.
