Hi,
after a restart of two DN from the HDFS the Impala daemon refused to start becuase it was not able to access /var/run/hdfs-sockets/dn. I verified the directory, and the socket is not there. I checked other DN hosts and there the socket directory is created.
I had to start the Impala, so I turned off short circuit reads, but my question is how to re-create these socket directories? Just with a restart of the HDFS?
Does anybody had a similar experience?
Thanks
