Most of the changes are simply moving code around. The main class to inspect is ShuffleBlockFetcherIterator. Review guide: - Most of the ConnectionManager code is now in network.cm package - ManagedBuffer is a new buffer abstraction backed by several different implementations (file segment, nio ByteBuffer, Netty ByteBuf) - BlockTransferService is the main internal interface introduced in this PR - NioBlockTransferService implements BlockTransferService and replaces the old BlockManagerWorker - ShuffleBlockFetcherIterator replaces the told BlockFetcherIterator to use the new interface TODOs that should be separate PRs: - Implement NettyBlockTransferService - Finalize the API/semantics for ManagedBuffer.release() Author: Reynold Xin Closes #2240 from rxin/blockTransferService and squashes the following commits: 64cd9d7 [Reynold Xin] Merge branch 'master' into blockTransferService

Two basic changes: 1) Instead of allowing MAX_NUM_RETRY abnormal Executor exits over the entire lifetime of the Application, allow that many since any Executor successfully began running the Application; 2) Don't remove the Application while Master still thinks that there are RUNNING Executors. This should be fine as long as the ApplicationInfo doesn't believe any Executors are forever RUNNING when they are not. I think that any non-RUNNING Executors will eventually no longer be RUNNING in Master's accounting, but another set of eyes should confirm that. This PR also doesn't try to detect which nodes have gone rogue or to kill off bad Workers, so repeatedly failing Executors will continue to fail and fill up log files with failure reports as long as the Application keeps running.

This works well, but can't cover some corner case like `select t.a.b from table as t`: `t.a.b` parsed as `GetField(GetField(UnResolved("t"), "a"), "b")` instead of `GetField(UnResolved("t.a"), "b")` using this new grammar. However, we can't resolve `t` as it's not a filed, but the whole table.(if we could do this, then `select t from table as t` is legal, which is unexpected) My solution is: dotExpressionHeader : ident "." ident baseExpression : expression "[" expression "]" | expression "." ident | ... | dotExpressionHeader | ident | ... I passed all test cases under sql locally and add a more complex case. "arrayOfStruct.field1 to access all values of field1" is not supported yet.
