From fb6c0cbac414f3c43dec2ab886ca8a1097b781f7 Mon Sep 17 00:00:00 2001 From: Josh Rosen Date: Fri, 6 Feb 2015 11:47:32 -0800 Subject: [PATCH 01/27] [HOTFIX] Fix test build break in ExecutorAllocationManagerSuite. This was caused because #3486 added a new field to ExecutorInfo and #4369 added new tests that created ExecutorInfos.

The reason is that: for something like `a.b[0].c.d`, we first parse it to `GetField(GetField(GetItem(Unresolved("a.b"), 0), "c"), "d")`. Then in `LogicalPlan#resolve`, we resolve `"a.b"` and build a `GetField` chain from bottom(the relation). But for the 2 outer `GetFiled`, we have to resolve them in `Analyzer` or do it in `GetField` lazily, check data type of child, search needed field, etc. which is similar to what we have done in `LogicalPlan#resolve`. So in this PR, the fix is just copy the same logic in `LogicalPlan#resolve` to `Analyzer`, which is simple and quick, but I do suggest introduce `UnresolvedGetFiled` like I explained in https://github.com/apache/spark/pull/2405.

For the input/output metrics, it just appends the counter every time the iterators get accessed. For shuffle on the write side, we count the metrics post aggregation (after a map side combine) and on the read side we count the metrics pre aggregation. This allows both the bytes read/written metrics and the records read/written to line up. For backwards compatibility, if we deserialize an older event that doesn't have record metrics, we set the metric to -1.

This PR targets standalone cluster mode, but is implemented in a general enough manner that can be potentially extended to other modes in the future. Client mode is currently not included in the changes here because there are many more Akka messages exchanged there. As of the changes here, the Master will advertise two ports, 7077 and 6066. We need to keep around the old one (7077) for client mode and older versions of Spark submit. However, all new versions of Spark submit will use the REST gateway (6066). By the way this includes ~700 lines of tests and ~200 lines of license.
