Amareshwari Sriramadasu commented on MAPREDUCE-1322: ---------------------------------------------------- Looks like "mapreduce.jobtracker.staging.root.dir" is not added in mapred-default.xml, but is added to src/test/mapred-site.xml. Streaming tests do not pick mapred-site.xml from src/test/. Is there any reason for not adding the configuration in mapred-default.xml? > TestStreamingAsDifferentUser fails on trunk > ------------------------------------------- > > Key: MAPREDUCE-1322 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1322 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: contrib/streaming, test > Affects Versions: 0.22.0 > Reporter: Amareshwari Sriramadasu > Fix For: 0.22.0 > > > TestStreamingAsDifferentUser fails on trunk with following exception : > Can not create a Path from a null string > java.lang.IllegalArgumentException: Can not create a Path from a null string > at org.apache.hadoop.fs.Path.checkPathArg(Path.java:78) > at org.apache.hadoop.fs.Path.<init>(Path.java:90) > at > org.apache.hadoop.mapred.ClusterWithLinuxTaskController.createHomeAndStagingDirectory(ClusterWithLinuxTaskController.java:158) > at > org.apache.hadoop.mapred.ClusterWithLinuxTaskController.startCluster(ClusterWithLinuxTaskController.java:147) > at > org.apache.hadoop.streaming.TestStreamingAsDifferentUser.testStreaming(TestStreamingAsDifferentUser.java:49) > The corresponding line for the exception : > {code} > Path stagingArea = new Path(conf.get(JTConfig.JT_STAGING_AREA_ROOT)); > {code} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
