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.
