Hi All. I am trying to configure elasticsearch hadoop repository against kerberized and SSL protected HDFS. I can successfully autenticate against kerberos, but is giving me this error creating a repository: [2017-06-06 03:37:19,882][INFO][org.apache.hadoop.security.UserGroupInformation] Login successful for user elasticsearch/ using keytab file /tmp/elastic.ktb [2017-06-06 03:37:20,130][ERROR][org.apache.hadoop.hdfs.DFSClient] Failed to close inode 796273 java.io.IOException: DataStreamer Exception: at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:563) Caused by: java.lang.NullPointerException at org.apache.hadoop.crypto.CryptoInputStream.(CryptoInputStream.java:133) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.DataTransferSaslUtil.createStreamPair(DataTransferSaslUtil.java:345) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.doSaslHandshake(SaslDataTransferClient.java:490) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.getEncryptedStreams(SaslDataTransferClient.java:299) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.send(SaslDataTransferClient.java:242) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.checkTrustAndSend(SaslDataTransferClient.java:211) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.socketSend(SaslDataTransferClient.java:183) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.createBlockOutputStream(DFSOutputStream.java:1289) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.nextBlockOutputStream(DFSOutputStream.java:1237) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:449) [2017-06-06 03:37:20,131][INFO][repositories] [[lnx-eus2dw-6892890b.bcidatalake.cl](http://lnx-eus2dw-6892890b.bcidatalake.cl)] update repository [diego\_hdfs\_repository] [2017-06-06 03:37:20,174][WARN][org.apache.hadoop.hdfs.DFSClient] DataStreamer Exception java.lang.NullPointerException at org.apache.hadoop.crypto.CryptoInputStream.(CryptoInputStream.java:133) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.DataTransferSaslUtil.createStreamPair(DataTransferSaslUtil.java:345) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.doSaslHandshake(SaslDataTransferClient.java:490) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.getEncryptedStreams(SaslDataTransferClient.java:299) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.send(SaslDataTransferClient.java:242) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.checkTrustAndSend(SaslDataTransferClient.java:211) at org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.socketSend(SaslDataTransferClient.java:183) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.createBlockOutputStream(DFSOutputStream.java:1289) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.nextBlockOutputStream(DFSOutputStream.java:1237) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:449) Any ideas on how to create/configure a hdfs repository using SSL?

Hi James. Thanks for answer. I think is not the same case. In the link you provided the error is no\_class\_def\_found\_error, but in my case is NullPointerException. I tried to put the missing jar in the repo folder without success. I think is because i dont know how to configure the SSL certificates for hdfs repository. Can you give me some light in how can i do it? thanks for your help. ( btw the elasticsearch version i am using is 2.4.3 ) ---
