Exception Summary

Exception	Description
CommitFailedException	This exception is raised when an offset commit with KafkaConsumer.commitSync() fails with an unrecoverable error.
InvalidOffsetException	Thrown when the offset for a set of partitions is invalid (either undefined or out of range), and no reset policy has been configured.
LogTruncationException	In the event of an unclean leader election, the log will be truncated, previously committed data will be lost, and new data will be written over these offsets.
NoOffsetForPartitionException	Indicates that there is no stored offset for a partition and no defined offset reset policy.
OffsetOutOfRangeException	No reset policy has been defined, and the offsets for these partitions are either larger or smaller than the range of offsets the server has for the given partition.
RetriableCommitFailedException
