Hi,   We use an hbase-indexer for NRT indexing an hbase table and from time to time cell values cause a CharConversionException when the document is sent to Solr. As we cannot guarantee 100% error-free data I would like to catch this exception in the mapper for further investigation and drop the value. I think a suitable place would be com.ngdata.hbaseindexer.indexer.Indexer.indexRowData(). Is there some configuration option to either make a character conversion issue non-fatal or replace the indexer with a custom class? I tried to replace the mapper but to no avail. As soon as the configuration is active it does not index anymore but without logging any error messages.   How would you fix such an issue? I thought about patching hbase-indexer-engine and suggest a code improvement but maybe there is an easier way?   We use CDH 5.0.1.
