@DataYogi, IPv4 is a function of your OS networking, so that is a matter for your host and network configuration. My point is that if you are unfamiliar with how database servers and other servers interact over IPv6, perhaps it would be best to only use IPv4 for now. See the following postgres information regarding addresses (including IPv6) https://www.postgresql.org/docs/9.3/static/auth-pg-hba-conf.html It appears you were missing the /64 subnet portion of the IP as your interface shows: inet6 addr: 2402:1f00:8001:281::/64 Scope:Global I believe either of the following in the pg_hba.conf file would allow access from that one host: host hue hue 2402:1f00:8001:281::/64 md5 or host hue hue 2402:1f00:8001:281::/128 md5 Unless you need to restrict access, you can add lines to allow access from any host that is IPv6 with the following: host hue hue ::0/0 md5 NOTE: Make sure you ensure there are no servers connecting to the embedded postgres database and restart from the command line with "service cloudera-scm-server-db restart" after making any changes to ensure they took effect.

We're just upgrading from 5.7 to 5.12 and received the same warning. In our case Hive metastore heap size is 12G so the max message size will be set to 1.2 G . That appears bit scary to me. What are the risks of setting the value such high ? How can we handle large metastore updates in case that happens ? Do we need to prepare the metastore server i.e. mysql to do somethign differently ? What happens if we don't follow this recommandation ? Thanks, Sunil

I installed my cluster (CDH 5.10.0) using packages. I would like to try Spark2, but noticed it is currently only available as a parcel. I can't find any instructions for my situation. So my question is: is it possible to install the Spark2 parcel on my cluster, even though my cluster was originally installed by using packages?
