[1/2] git commit: ACCUMULO-1973 Add a warning if we don't find
non-default values for namenode configuration
Updated Branches:
refs/heads/1.5.1-SNAPSHOT 652b5af39 -> 536211b3c
ACCUMULO-1973 Add a warning if we don't find non-default values for namenode configuration
This is one of biggest confusions that new users seem to run into when
trying to initialize Accumulo (as it's a problem with us not finding
Hadoop configurations). Hadoop will work properly, as its configuration
is likely correct, but Accumulo can't find core-site.xml, tries to write
to the root of the local fs, and fails. Try to be a bit more explicit
about what happened when we initialized and the Configuration from the FS.
