Subject Re: How to remove all tables of accumulo or format hadoop files for accumulo
Date Fri, 28 Apr 2017 08:08:21 GMT
For deleting test tables, you may find the flag "-p" for the deletetable
shell command useful.  For example,

deletetable -f -p Test.*

will delete all tables that begin with the prefix "Test".  You could even
call this from a script if you want to automate it into your build.
Perhaps this would solve your problem without having to re-format HDFS.
