[jira] [Commented] (MAPREDUCE-3782) teragen terasort jobs fail when
using webhdfs://
[ https://issues.apache.org/jira/browse/MAPREDUCE-3782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13198136#comment-13198136 ]
Arpit Gupta commented on MAPREDUCE-3782:
----------------------------------------
here are the steps to reproduce the issue (make sure webhdfs is enabled)
1. run teragen
bin/hadoop --config HADOOP_CONF_DIR jar hadoop-mapreduce-examples-0.23.1-SNAPSHOT.jar teragen 10000 webhdfs://NN:50070/user/path
prints the following
{code}
12/02/01 20:03:33 INFO hdfs.DFSClient: Created HDFS_DELEGATION_TOKEN token 158 for hrt_qa on 98.137.234.231:8020
12/02/01 20:03:33 INFO security.TokenCache: Got dt for hdfs://NN:8020;uri=IP:8020;t.service=IP:8020
{code}
Since a webhdfs url was provided a webhdfs delegation token should have been used.
2. Run terasort
bin/hadoop --config HADOOP_CONF_DIR jar hadoop-mapreduce-examples-0.23.1-SNAPSHOT.jar terasort webhdfs://NN:50070/user/path webhdfs://NN:50070/user/path2
This gets 2 delegation tokens one webhdfs and the other hdfs
{code}
12/02/01 20:03:48 INFO terasort.TeraSort: starting
12/02/01 20:03:49 INFO security.TokenCache: Got dt for webhdfs://NN:50070;uri=IP:50070;t.service=IP:50070

12/02/01 20:03:51 INFO hdfs.DFSClient: Created HDFS_DELEGATION_TOKEN token 161 for USER on 98.137.234.231:8020
12/02/01 20:03:51 INFO security.TokenCache: Got dt for hdfs://NN:8020;uri=IP:8020;t.service=IP:8020
{code}
Both the tokens should be webhdfs delegation tokens.
Then we see a java io exception and the job fails. Below is the stack trace
{code}
