Example 1 with MetaMutationAnnotation

use of org.apache.hadoop.hbase.MetaMutationAnnotation in project hbase by apache.

the class MergeTableRegionsProcedure method preMergeRegionsCommit.

/**
 * Post merge region action
 * @param env MasterProcedureEnv
 */
private void preMergeRegionsCommit(final MasterProcedureEnv env) throws IOException {
    final MasterCoprocessorHost cpHost = env.getMasterCoprocessorHost();
    if (cpHost != null) {
        @MetaMutationAnnotation final List<Mutation> metaEntries = new ArrayList<>();
        cpHost.preMergeRegionsCommit(regionsToMerge, metaEntries, getUser());
        try {
            for (Mutation p : metaEntries) {
                RegionInfo.parseRegionName(p.getRow());
            }
        } catch (IOException e) {
            LOG.error("Row key of mutation from coprocessor is not parsable as region name. " + "Mutations from coprocessor should only be for hbase:meta table.", e);
            throw e;
        }
    }
