Aleksandr Sorokoumov updated CASSANDRA-10968:
---------------------------------------------
Reviewer: Alex Petrov
Fix Version/s: 2.1.12
Reproduced In: 2.2.4, 2.1.12 (was: 2.1.12, 2.2.4)
Status: Patch Available (was: Open)
I was able to reproduce the behavior described in
http://www.mail-archive.com/user%40cassandra.apache.org/msg42019.html by
creating a snapshot on a table with 2 columns and a secondary index:
{CODE}
CREATE KEYSPACE X
WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };
USE X;
CREATE TABLE table1 (
col1 varchar,
col2 varchar,
PRIMARY KEY (col1, col2)
);
CREATE INDEX col2_idx ON X.table1 (col2);
INSERT INTO x.table1 (col1, col2) VALUES ('a1', 'a2');
INSERT INTO x.table1 (col1, col2) VALUES ('b1', 'b2');
{CODE}
Before the patch, branch cassandra-2.1.12:
{CODE}
$ bin/nodetool snapshot x
Requested creating snapshot(s) for [x] with snapshot name [1491658291872]
Snapshot directory: 1491658291872
$ cat
data/data/x/table1-a47092a01aa011e7b2e959ff5fdd622a/snapshots/1491658291872/manifest.json
{"files":["x-table1.col2_idx-ka-1-Data.db"]}
{CODE}
In the manifest above the index table is missing.
After the patch:
{CODE}
$ git checkout 10968-2.1.12
previous HEAD position was a6619e56b1... bump 2.1 versions
Switched to branch '10968-2.1.12'
$ bin/nodetool snapshot x
Requested creating snapshot(s) for [x] with snapshot name [1491658830545]
Snapshot directory: 1491658830545
$ cat
data/data/x/table1-a47092a01aa011e7b2e959ff5fdd622a/snapshots/1491658830545/manifest.json
{"files":["x-table1-ka-1-Data.db","x-table1.col2_idx-ka-1-Data.db"]}
{CODE}

> xNoticed indeterminate behaviour when taking snapshot on column families that
> has secondary indexes setup. The created manifest.json created when doing
> snapshot, sometimes contains no file names at all and sometimes some file
> names.
