Subject Re: BulkloadTool issue even after successful HfileLoads
Date Wed, 23 Sep 2015 13:24:34 GMT
Hi Dhruv,

This is a bug in Phoenix, although it appears that your hadoop
configuration is also somewhat unusual.

As far as I can see, your hadoop configuration is set up to use the
local filesystem, and not hdfs. You can test this by running the
following command:

    hadoop dfs -ls /

If that command lists the contents of the root directory on your local
machine, then hadoop is set up to use your local filesystem, and not
HDFS.

The bulk load tool currently uses the file system that is configured
for Hadoop for deleting the (temporary) output directory. However,
because your setup uses the local filesystem by default, but you're
using HDFS via the file paths that you supply to the tool, deleting
the temporary output directory fails.

The quick fix (if feasible) is to set up your hadoop command to use
HDFS as the default file system. However, could you also log this as a
bug in the JIRA (https://issues.apache.org/jira/browse/PHOENIX)

- Gabriel
