Summary: Concurrent WAL replay & log may fail with CRC error on read Key: IGNITE-11687 URL: https://issues.apache.org/jira/browse/IGNITE-11687 Project: Ignite Issue Type: Bug Reporter: Alexey Goncharuk The cause is the way {{end}} is calculated for WAL iterator: {code} if (hnd != null) end = hnd.position(); {code} {code} @Override public FileWALPointer position() { lock.lock(); try { return new FileWALPointer(getSegmentId(), (int)written, 0); } finally { lock.unlock(); } } {code} Consider a partially written entry. In this case, {{written}} has been already updated, concurrent WAL replay will attempt to read the incompletely written record and since {{end}} is not null, iterator will fail with CRC error. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
