Hi Brian and the team,
Thanks for making the tools available for us. I just noticed a glitch
in HBaseClient.java; HTable is set to non auto-flush mode, but there
is no place that calls flushCommits() explicitly to push the
uncommitted changes to HBase. When I run -load command with one
million records to insert, I'll only get something like 998,582 loaded
on the table.
This code fragment should fix the problem:
public void cleanup() throws DBException {
try {
if (_hTable != null) {
_hTable.flushCommits();
}
} catch (IOException e) {
throw new DBException(e);
}
}
Thanks,
