I can't reproduce the issue with my simple code:
```scala
spark.streams.addListener(new StreamingQueryListener {
override def onQueryProgress(event:
StreamingQueryListener.QueryProgressEvent): Unit = {
println(event.progress.id + " is on progress")
println(s"My accu is
Hi,
We have a Spark 2.4 job failed on Checkpoint recovery every few hours with
the following errors (from the Driver Log):
driver spark-kubernetes-driver ERROR 20:38:51 ERROR MicroBatchExecution:

Hi, anyone knows the behavior of dropping managed tables in case of
external hive meta store:
Deletion of the data (e.g. from object store) happens from Spark sql or,
the external hive metastore ?
Confused by local mode and remote mode codes.
I am assuming StateUpdateTask is your application specific class. Does it
have 'updateState' method or something? I googled but couldn't find any
documentation about doing it this way. Can you please direct me to some
documentation. Thanks.

You can’t play much if it is a streaming job. But in case of batch jobs,
sometimes teams will copy their S3 data to HDFS in prep for the next run :D

I don't think so, that data is inherently ambiguous and incorrectly
formatted. If you know something about the structure, maybe you can rewrite
the middle column manually to escape the inner quotes and then reparse.

Is there any way I can handle it in code?
Thanks,

Your data doesn't escape double-quotes.

Hi team,
I am loading an CSV. One column contains a json value. I am unable to parse
that column properly. Below is the details. Can you please check once?
val df1=spark.read.option("inferSchema","true").
option("header","true").option("quote", "\"")
.option("escape",
Giving the code below:
//accumulators is a class level variable in driver.
sparkSession.streams().addListener(new StreamingQueryListener() {
@Override
public void onQueryStarted(QueryStartedEvent queryStarted) {
logger.info("Query started: " +
May I get how the accumulator is accessed in the method `onQueryProgress()`?
AFAICT, the accumulator is incremented well. There is a way to verify that
in cluster like this:
```
// Add the following while loop before invoking awaitTermination
while (true) {
println("My acc: " +
See if this helps
"That is to say, on a per node basis, HDFS can yield 6X higher read
throughput than S3. Thus, *given that the S3 is 10x cheaper than HDFS, we
find that S3 is almost 2x better compared to HDFS on performance per
dollar."*
yes, I am using stateful structured streaming. Yes similar to what you do.
This is in Java
I do it this way:
Dataset productUpdates = watermarkedDS
.groupByKey(
(MapFunction) event ->
event.getId(), Encoders.STRING())
.mapGroupsWithState(
Thanks Fabiano. I am building one myself. Will surely use yours as quick
starter.

Ok, thanks for the update Sean.
Can I also track RC vote?
