Package org.apache.accumulo.server.metanalysis Description

Provides programs to analyze metadata mutations written to write ahead logs.

These programs can be used when write ahead logs are archived. The best way to find which write ahead logs contain metadata mutations is to grep the tablet server logs. Grep for events where walogs were added to metadata tablets, then take the unique set of walogs.

To use these programs, use IndexMeta to index the metadata mutations in walogs into Accumulo tables. Then use FindTable and PrintEvents to analyze those indexes. FilterMetaiallows filtering walogs down to just metadata events. This is useful for the case where the walogs need to be exported from the cluster for analysis.
