caiconghui opened a new issue #3671:
URL: https://github.com/apache/incubator-doris/issues/3671
Now, the connection timeout and socket timeout is set to be 0 which may
cause many threads stuck in java.net.SocketInputStream.socketRead0 and can
never be reused.
The Problem is like the following:
"thrift-server-pool-2493" #2999 daemon prio=5 os_prio=0
tid=0x00007f77341e2000 nid=0x3b5c runnable [0x00007f750501e000]

When thrift client crash or encounter some network problem , the thrift
server pool thread may stuck in java.net.SocketInputStream.socketRead0 which
cause the connection leak, so we need a thrift_client_timeout_ms config to
prevent this problem.
