  • Method Details

    • hasSegmentState

      boolean hasSegmentState()
      optional .hadoop.hdfs.qjournal.SegmentStateProto segmentState = 1;
      Returns:
      Whether the segmentState field is set.

    • getSegmentState

      QJournalProtocolProtos.SegmentStateProto getSegmentState()
      optional .hadoop.hdfs.qjournal.SegmentStateProto segmentState = 1;
      Returns:
      The segmentState.

    • getSegmentStateOrBuilder

      QJournalProtocolProtos.SegmentStateProtoOrBuilder getSegmentStateOrBuilder()
      optional .hadoop.hdfs.qjournal.SegmentStateProto segmentState = 1;

    • hasAcceptedInEpoch

      boolean hasAcceptedInEpoch()
      optional uint64 acceptedInEpoch = 2;
      Returns:
      Whether the acceptedInEpoch field is set.

    • getAcceptedInEpoch

      long getAcceptedInEpoch()
      optional uint64 acceptedInEpoch = 2;
      Returns:
      The acceptedInEpoch.

    • hasLastWriterEpoch

      boolean hasLastWriterEpoch()
      required uint64 lastWriterEpoch = 3;

      Whether the lastWriterEpoch field is set.

    • getLastWriterEpoch

      long getLastWriterEpoch()
      required uint64 lastWriterEpoch = 3;
      Returns:
      The lastWriterEpoch.

    • hasLastCommittedTxId

      boolean hasLastCommittedTxId()
       The highest committed txid that this logger has ever seen.
 This may be higher than the data it actually has, in the case
 that it was lagging before the old writer crashed.
      optional uint64 lastCommittedTxId = 4;
      Returns:
      Whether the lastCommittedTxId field is set.

    • getLastCommittedTxId

      long getLastCommittedTxId()
       The highest committed txid that this logger has ever seen.
 This may be higher than the data it actually has, in the case
 that it was lagging before the old writer crashed.
      optional uint64 lastCommittedTxId = 4;
      Returns:
      The lastCommittedTxId.
