Subject [jira] [Commented] (HBASE-16183) Correct errors in example program of coprocessor in Ref Guide
Date Tue, 12 Jul 2016 06:48:10 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16183?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15372276#comment-15372276

Xiang Li commented on HBASE-16183:

Hi [~jerryhe], [~carp84], would you please review the patch v1 at your most convenience?
The only divergence could be that I proposed the following code could be all removed when
overriding preGetOp() in class RegionObserverExample in section 90.1
List kvs = new ArrayList(results.size());
for (Cell c : results) {
preGet(e, get, kvs);
to make it as
public void preGetOp(final ObserverContext<RegionCoprocessorEnvironment> e, final Get
get, final List<Cell> results)
throws IOException {

  if (Bytes.equals(get.getRow(),ADMIN)) {
    Cell c = CellUtil.createCell(get.getRow(),COLUMN _FAMILY, COLUMN,
    System.currentTimeMillis(), (byte)4, VALUE);
