List of newEpoch() Examples

Examples of newEpoch()

org.apache.hadoop.hdfs.qjournal.client.IPCLoggerChannel.newEpoch()
org.apache.hadoop.hdfs.qjournal.server.Journal.newEpoch()
Try to create a new epoch for this journal. @param nsInfo the namespace, which is verified for consistency or used toformat, if the Journal has not yet been written to. @param epoch the epoch to start @return the status information necessary to begin recovery @throws IOException if the node has already made a promise to anotherwriter with a higher epoch number, if the namespace is inconsistent, or if a disk error occurs.
