Subject [0.90.1-cdh3u0] Setting Filter Lists to a client Scan
Date Tue, 17 May 2011 16:22:07 GMT
I am having a problem adding filerLists to my scans.  These are the standard
filters, nothing custom. When I use them on the client, I get the following
errors.  Maybe I need to include some additional jars on my classpath? I am
using row filters in the filter list.

pseudo-ish code:

Scan s = new Scan();
FilterList fl = new
FilterList(FilterList.Operator.MUST_PASS_ALL){addFilter(new
RowFilter(CompareFilter.CompareOp.NOT_EQUAL, new
SubstringComparator("|something|")));addFilter(new
RowFilter(CompareFilter.CompareOp.NOT_EQUAL, new
SubstringComparator("|somethingelse|")));}
s.setFilter(fl);

Hbase Version 0.90.1-cdh3u0
Client jars: zookeeper.jar, hadoop-core-0.20.2-cdh3u0.jar,
hbase-0.90.1-cdh3u0.jar
