Jerry He commented on HBASE-16970:
----------------------------------
Could we be more clear that " -1 means no caching specified and the value of
HBASE_CLIENT_SCANNER_CACHING (default to DEFAULT_HBASE_CLIENT_SCANNER_CACHING)
will be used"?
> Clarify misleading Scan.java comment about caching

> Project: HBase
> Issue Type: Bug

> Priority: Trivial
> Labels: documentation, patch

>
> The Scan class has an integer field, caching, that defaults to -1. The
> meaning of -1 is that the option was not overriden (aka not set) and
> therefore that the default configuration should be used.
> This trivial patch corrects the comment of that field to reflect this meaning
> rather than misleading the reader to believe that caching is disabled.
