Signed-off-by: joewitt <joew...@apache.org> > multiple putHDFS processors can result in put failures. > ------------------------------------------------------- > > Key: NIFI-1536 > URL: https://issues.apache.org/jira/browse/NIFI-1536 > Project: Apache NiFi > Issue Type: Bug > Components: Core Framework > Affects Versions: 0.5.0 > Environment: Java 1.8.0_60 > OSX Yosemite 10.10.5 > Reporter: Matthew Clarke > Assignee: Oleg Zhurakousky > Fix For: 0.6.0, 0.5.1 > > > When multiple putHDFS processors exist, the first to run loads some config > that is then used by other putHDFS processors that are started. > I have two dataflows setup. One pushes data to a kerberized HDFS cluster > while the other pushes data to a totally different non kerberized HDFS > cluster. > Each putHDFS is configured to use its own core-sites.xml. If I start the > putHDFS that sends to the Kerberized HDFS cluster first, the other putHDFS > will throw an error when it tries to send data to the non-kerberized HDFS > cluster. > ERROR [Timer-Driven Process Thread-7] o.apache.nifi.processors.hadoop.PutHDFS > java.io.IOException: Failed on local exception: java.io.IOException: Server > asks us to fall back to SIMPLE auth, but this client is configured to only > allow secure connections.; Host Details : local host is: "<client > hostname>/<client IP>"; destination host is: "<hdfs hostname>":<hdfs port> > .... > Caused by: java.io.IOException: Server asks us to fall back to SIMPLE auth, > but this client is configured to only allow secure connections. > Even if i stop the putHDFS that is sending to the kerberized HDFS and/or > restart the putHDFS sending to the non kerberized HDFS, the above error > persists. > I need to restart NiFi to clear condition.
