Pre-Upgrade Steps for Sqoop2
Complete the following steps before you upgrade Sqoop2 with or without the MapR Installer.
Procedure
-
Back up configuration files. Copy configuration files from
/opt/mapr/sqoop/sqoop-<version>/server/conf/sqoop.properties
to a location outside the MapR installation.For example, you can copy the file to a /tmp directory:cp /opt/mapr/sqoop/sqoop-<version>/server/conf/sqoop.properties /tmp/
-
Delete the Sqoop2 repository (/opt/mapr/sqoop/repository).
NOTE: Due to SQOOP-1593, you also should not create a backup of the Sqoop2 repository before you upgrade.

node.
maprcli node services -name sqoop2 -action stop -nodes <space delimited list of nodes>
