Hi,
I have the following problem after trying to upgrade my Java code to the RestHighLevelClient.
At the end of a big process of reindexation, there is an old piece of code that run a Force Merge.
I have replaced with a call to forcemergeAsync(), and expect that the process will be notified when the merge is finished (takes ~20 minutes for very big indices), but the query seems to wait and the socket die with a SocketTimeoutException (That's normal).
My questions are:
What is the good way to run this kind of long query ?
Is there a problem in Java client or is my code bad ? I can believe it
Do I have to run it in a task and watch the task (seems to be the good solution) ?
Here is the code:
logger.info("### Force merge...");
final CountDownLatch countDownLatch = new CountDownLatch(1);
ActionListener<ForceMergeResponse> listener = new ActionListener<ForceMergeResponse>() {
@Override
public void onResponse(ForceMergeResponse response) {
isOk.set(true);
countDownLatch.countDown();
}
@Override
public void onFailure(Exception e) {
isOk.set(false);
logger.severe(ExceptionUtils.getFullStackTrace(e));
countDownLatch.countDown();
}
};
client.indices().forcemergeAsync(
new ForceMergeRequest(indexName).maxNumSegments(forceMergeMaxNumSegments) /*.createTask(id, type, action, parentTaskId, headers)*/,
RequestOptions.DEFAULT,
listener);
// wait max 1h for async request to perform the merge request
boolean finishNormaly = countDownLatch.await(1, TimeUnit.HOURS);
if(!finishNormaly) {
throw new InterruptedException();
}
After 30s, the onFailure is called, and that's bad for me
Thank you,
Xavier
