I had the same issue on one of the node and it was related with /etc/resolv.conf entry. Changed the nameserver details to that of other nodes and that fixed it.

Hello Basically the desktop.middleware is missing. To check it run below commands: 1. $ hue-3.9.0/build/env/bin/python In the Python prompt type below commands > import sys > 'desktop.middleware' in sys.modules (The output for this would be False) > import desktop.middleware > desktop.middleware' in sys.modules (The output for this would be True if the lib exists)

I found this discussion and noticed that the error "Impala is not supported for RHEL7" can appear in CM 5.11 if you try to install Impala via parcel. Since 2015 and on, Impala is included in the main CDH parcel, and is simply added as a service to the cluster. If you try to add via parcel on RHEL7 (or centos7), you are in effect trying to add an old version (2.0 or earlier) of Impala, and in that case, the statement "Impala is not supported for RHEL7" is actually true. I expect this misleading error message will occur for any attempt on any CM ver. to add Impala via parcels on RHEL7. I hope this clarification helps someone.

You mentioned that you still need to fix the 'Under-Replicated Blocks'. This is what I found with google to fix: $ su - <$hdfs_user> $ hdfs fsck / | grep 'Under replicated' | awk -F':' '{print $1}' >> /tmp/under_replicated_files $ for hdfsfile in `cat /tmp/under_replicated_files`; do echo "Fixing $hdfsfile :" ; hadoop fs -setrep 3 $hdfsfile; done
