             Summary: libhdfs++: Improve C API error reporting
                 Key: HDFS-11544
                 URL: https://issues.apache.org/jira/browse/HDFS-11544
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: James Clampffer
            Assignee: James Clampffer


The thread local string used for hdfsGetLastError wasn't reset between calls so it could give stale results in confusing ways.  Now it gets reset with a placeholder that says that <functionname> hasn't set an error string.

Also fixed indentation that wasn't consistent + marked which functions are used by the hdfs.h API and hdfs_ext.h API to make it easier to see when changes could break compatibility.  Included some minor cleanup for the common case catch blocks.
