ASF GitHub Bot commented on BAHIR-183: -------------------------------------- Github user lukasz-antoniak commented on the issue: https://github.com/apache/bahir/pull/72 Would it be possible to implement integration tests with embedded HDFS just to make sure we do not run into regression issues? > Using HDFS for saving message for mqtt source > --------------------------------------------- > > Key: BAHIR-183 > URL: https://issues.apache.org/jira/browse/BAHIR-183 > Project: Bahir > Issue Type: Improvement > Components: Spark Structured Streaming Connectors > Affects Versions: Spark-2.2.0 > Reporter: Wang Yanlin > Priority: Major > Fix For: Spark-2.2.1 > > > Currently in spark-sql-streaming-mqtt, the received mqtt message is saved in > a local file by driver, this will have the risks of losing data for cluster > mode when application master failover occurs. So saving in-coming mqtt > messages using a director in checkpoint will solve this problem. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
