| Description |
|
When using mongoimport tool to insert sample data (100000000 rows totally), The shard environment contains 2 Shards , 2 Shards + 2 Replicas, 4 Shards + 4 Replicas. When chunkSize is set to 50MB, the mongos log contains too many autosplit failure.such as I think the autosplit process failure is normal when use small chunkSize. the attachment contains all logs when using 2 shards. |

The attachment files have contained all the logs in the test process. I will try the test with 1.7.3 and 1.6.5, but I prefer to choose a stable release in our production enviorment. |
