Re: CachedKafkaConsumer: CachedKafkaConsumer is not running in UninterruptibleThread warning

These issues have likely been solved in future versions. Please use the
latest release - Spark 2.3.0.

Re: CachedKafkaConsumer: CachedKafkaConsumer is not running in UninterruptibleThread warning

[Junfeng Chen]

Spark 2.1.1.

Actually it is a warning rather than an exception, so there is no stack
trace. Just many this line:

Re: CachedKafkaConsumer: CachedKafkaConsumer is not running in UninterruptibleThread warning

[Tathagata Das]

Which version of Spark are you using? And can you give us the full stack
trace of the exception?

CachedKafkaConsumer: CachedKafkaConsumer is not running in UninterruptibleThread warning

[Junfeng Chen]

I am trying to read kafka and save the data as parquet file on hdfs
according to this
https://stackoverflow.com/questions/45827664/read-from-kafka-and-write-to-hdfs-in-parquet



The code is similar to :

val df = spark
  .read
  .format("kafka")
  .option("kafka.bootstrap.servers", "host1:port1,host2:port2")
  .option("subscribe", "topic1")
  .load()

while I am writing in Java.

However, I keep throwing the following warning:
CachedKafkaConsumer: CachedKafkaConsumer is not running in
UninterruptibleThread. It may hang when CachedKafkaConsumer's method are
interrupted because of KAFKA-1894.

How to solve it? Thanks!
