Subject: Cluster instability due to java.net.SocketTimeoutException: Read timed
out
Hello all,
sometime the cluster is unstable due to "read time out".
Is here any parameter which I can fine tuning in order to reduce this problem ?
Most timeouts (66%) are coming from
com.sun.jersey.api.client.ClientHandlerException
few (33%) from
o.apache.nifi.controller.FlowController
Thanks in adavance
AP
