"hadoop dfs -put" does not return nonzero status on failure
-----------------------------------------------------------
Key: HADOOP-3993
URL: https://issues.apache.org/jira/browse/HADOOP-3993
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.18.0
Reporter: Karl Anderson
I'm attempting to put a file on DFS with the "hadoop dfs -put" command. The
put is failing, probably because my cluster is still being initialized, but the
command is still returning a status of 0.
If there was a meaningful error status, I'd be able to handle the situation (in
my case, waiting and putting again works).
The output is telling me there is a NotReplicatedYetException; it's a new
cluster and the nodes are still being initialized.
Here's the beginning of the output; it tries a few times, but eventually gives
up.
executing: source ~/.bash_profile; hadoop dfs -put ./vectorfile input/vectorfile
