Hello!
I am using the JDBC river plugin (latest version with the name
"elasticsearch-river-jdbc-2.2.1.jar" on ES 0.90.5) over some very large
views and, so, I wait for the bulk requests to finish, count the total
number of indexed documents to see if it is alright, and delete the river.
Everything has been working fine for some months now.
I am using a cluster with two nodes sharing the same configuration and,
recently, I started noticing that when I delete the river I receive an
enormous amount of error messages (every one to five ms for a few minutes)
stating that it "Caught exception while handling client http traffic,
closing connection".
The success message for the deletion of the river appears in the slave
node (Goblyn), and the error ones in the master (Corsi, Tom). The error
messages appear to be related to the bulk requests that have already
finished, Is some clean up process still going on?
It seems clear that the slave node was still connected to the master
(9200) on all these ports (50508, 50501, etc.) while it requested the
deletion of the river and that, after this deletion, those connections were
forcefully closed. What should I be doing here? How should I check with ES
if it is ok to delete a river? Even though the river is "oneshot" I am
deleting the river because it would always duplicate my documents when
starting ES.
Thanks for your help!

P.S.: ElasticSearch rocks! And I am a huge fan of the JDBC river.
