I was trying to do the Maintenance update with MapR Installer on my MapR - 5.2.2, 7 node cluster, but node1 failed with this error,

i was trying with "Incremental Install" too...but getting the same error!!!

please find the attached log from the failed node.
Would really appreciate your assistance in this.
