Preference wise (as Impact on running cluster will also be very less):- cluster replication:- If requirement is to recover in realtime and new cluster can be afforded. export snapshot:- if recovery to last taken snapshot is fine and cost of this approach is less as you can export it to any cheap storage(hdfs,s3 or anything). But with this incremental backup will not be possible, old backups will become obsolete with the new.

Append HBASE_CLASSPATH to HADOOP_CLASSPATH like below:- export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HBASE_CLASSPATH //but before that confirm HBASE_CLASSPATH is properly set. And also you may need to set hive.aux.jars.path in hive-site.xml so that libraries are available in MR job. <property>
<name>hive.aux.jars.path</name>
<value><hive_home>/lib/hive-hbase-handler-<version>.jar,
<hbase_home>/lib/hbase-client-<version>.jar, <hbase_home>/lib/hbase-server-<version>.jar,<hbase_home>/lib/hbase-protocol-<version>.jar,<hbase_home>/lib/zookeeper-<version>.jar</value>
<description>A comma separated list (with no spaces) of the jar files required for Hive-HBase integration</description>
</property> replace the above paths with actual paths as per your setup.

I am not able to access the logs attached by you. Is it possible for you to share the logs through some shared ftp links? would be intereseted in zookeeper logs, gc logs, datanodes logs, hbase regionserver logs, hbase master logs as well.

Upgrading any component out of HDP is not recommended , however, you can upgrade to phoenix 4.6 with just changing phoenix-server.jar on all nodes with phoenix-4.6 server jar and upgrading client jar to phoenix-4.6 . Updates in the schema will be automatically taken care by new phoenix-client jar. And just look for upgrade option in bin/psql.py. u,--upgrade Upgrades tables specified as arguments by
rewriting them with the correct row key for
descending columns. If no arguments are
specified, then tables that need to be
upgraded will be displayed without being
upgraded. Use the -b option to bypass the
rewrite if you know that your data does not
need to be upgrade. This would only be the
case if you have not relied on auto padding
for BINARY and CHAR data, but instead have
always provided data up to the full max
length of the column. See PHOENIX-2067 and
PHOENIX-2120 for more information. Note
that phoenix.query.timeoutMs and
hbase.regionserver.lease.period parameters
must be set very high to prevent timeouts
when upgrading.
if you have data affected by above jira tickets.

@Artem Ervits, Not now.. as we don't recommend to use local index in production yet. Local Index will probably be ready for production in next HDP release(but not sure) and this connection made (which access meta/namespace tables) during preScannerOpen will be moved to different place to avoid above problem.,

Hi @Pedro Gandola
This problem occurs when meta regions are not assigned yet and preScannerOpen coprocessor waits for reading meta table for local indexes, which results in openregionthreads to wait forever because of deadlock. you can solve this by increasing number of threads required to open the regions so that meta regions can be assigned even threads for local index table is still waiting to remove the deadlock. <property>
<name>hbase.regionserver.executor.openregion.threads</name>
<value>100</value>
</property>
