--------------------------------
Summary: seen_txid in the shared edits directory is modified
during bootstrapping
Key: HDFS-9533
URL: https://issues.apache.org/jira/browse/HDFS-9533
Project: Hadoop HDFS
Issue Type: Bug
Components: ha, namenode
Affects Versions: 2.6.0
Reporter: Kihwal Lee
The last known transaction id is stored in the seen_txid file of all known
directories of a NNStorage when starting a new edit segment. However, we have
seen a case where it contains an id that falls in the middle of an edit
segment. This was the seen_txid file in the sahred edits directory. The active
namenode's local storage was containing valid looking seen_txid.
