             Summary: Add option to egrep and RegExFilter for subsequence matching
                 Key: ACCUMULO-720
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-720
             Project: Accumulo
          Issue Type: Improvement
            Reporter: Keith Turner
             Fix For: 1.5.0


Egrep and RegExfilter use java Matcher.match() which only returns true if the expression matches the entire string.  Matcher.find() can detect when an expression matches a subsequence of the string.  Need an option to use find in egrep and RegexFilter.

This issue was created based on discussion in the following two mailing list threads.

 * [egrep usage - 1.3.4|http://mail-archives.apache.org/mod_mbox/accumulo-user/201207.mbox/%3CCAP19eqypCNAueE4z6TPU-Jt3g-%3DL2ptLVo9%2Bc_HC_LVA0LOTog%40mail.gmail.com%3E] July

Based on this discussion, -g and --global seem like good candidates for the options to add to egrep.
