Feng Zhu created CALCITE-3739: --------------------------------- Summary: Remove failed snapshot track file in Windows OS for Cassandra adapter Key: CALCITE-3739 URL: https://issues.apache.org/jira/browse/CALCITE-3739 Project: Calcite Issue Type: Bug Components: cassandra-adapter Reporter: Feng Zhu
In Windows OS, CassandraUnit leaves an extra "cassandra/.toDelete" snapshot track file. After migrating to Gradle, it is flagged as "unapproved license" and fails on "rat" task. It is annoying to manually delete this file every time. The issue is also mentioned in CALCITE-2442. But I found the snapshot file still exists with the fix. {code:java} @AfterClass public static void tearDown() { if (RULE instanceof CassandraCQLUnit) { CassandraCQLUnit rule = (CassandraCQLUnit) RULE; rule.getSession().close(); rule.getCluster().close(); // see https://issues.apache.org/jira/browse/CALCITE-2442 // see https://issues.apache.org/jira/browse/CASSANDRA-13085 // Is it done by cluster.close() already ? if (FBUtilities.isWindows) { WindowsFailedSnapshotTracker.deleteOldSnapshots(); } } } {code} I make some profling work. It seems that the snapshot track file is locked by other threads. "The process cannot access the file because it is being used by another process." Any ideas? -- This message was sent by Atlassian Jira (v8.3.4#803005)
