Flavio Pompermaier commented on FLINK-4628: ------------------------------------------- Could this be also the cause of https://issues.apache.org/jira/browse/FLINK-4061? > User class loader unavailable during input split assignment > ----------------------------------------------------------- > > Key: FLINK-4628 > URL: https://issues.apache.org/jira/browse/FLINK-4628 > Project: Flink > Issue Type: Bug > Components: JobManager > Affects Versions: 1.2.0, 1.1.2 > Reporter: Maximilian Michels > Assignee: Maximilian Michels > Priority: Minor > > {{InputFormat}}\s runs through two configuration phases in the {{JobManager}}. > 1. initializeOnMaster which runs the configure() method on the InputFormat > 2. createInputSplits when the ExecutionJobVertex is created > In 1 we set the user class loader as the context class loader of the > executing thread. > In 2 we only have the system class loader available. If any classes need to > be loaded then, we have a problem. Some InputFormats rely on code which > lazily load classes at different points in time. > In particular, this is a problem with the HBase TableInputFormat in the > latest master. > We should make the user class loader available when creating input splits. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
