Might be useful for restore of a backup using the HLogs. > This could an M/R (with a mapper per HLog file). > The tool would get a timerange and a (set of) table(s). We'd pick the right > HLogs based on time before the M/R job is started and then have a mapper per > HLog file. > The mapper would then go through the HLog, filter all WALEdits that didn't > fit into the time range or are not any of the tables and then uses > HFileOutputFormat to generate HFiles. > Would need to indicate the splits we want, probably from a live table. -- This message is automatically generated by JIRA.
