Tsz Wo (Nicholas), SZE updated HDFS-3100: ----------------------------------------- Description: STEP: 1, deploy a single node hdfs 0.23.1 cluster and configure hdfs as: A) enable webhdfs B) enable append C) disable permissions 2, start hdfs 3, run the test script as attached RESULT: expected: a file named testFile should be created and populated with 32K * 5000 zeros, HDFS should be OK. I got: script cannot be finished, file has been created but not be populated as expected, actually append operation failed. Datanode log shows that, blockscaner report a bad replica and nanenode decide to delete it. Since it is a single node cluster, append fail. It makes no sense that the script failed every time. Datanode and Namenode logs are attached. was: STEP: 1, deploy a single node hdfs 0.23.1 cluster and configure hdfs as: A) enable webhdfs B) enable append C) disable permissions 2, start hdfs 3, run the test script as attached RESULT: expected: a file named testFile should be created and populated with 32K * 5000 zeros, HDFS should be OK.
