Robbie Zhang resolved IMPALA-8595.
----------------------------------
Resolution: Fixed
Fix Version/s: Impala 3.3.0
> THRIFT-3505 breaks IMPALA-5775
> ------------------------------
>
> Key: IMPALA-8595
> URL: https://issues.apache.org/jira/browse/IMPALA-8595
> Project: IMPALA
> Issue Type: Bug
> Affects Versions: Impala 3.1.0
> Reporter: Robbie Zhang
> Assignee: Robbie Zhang
> Priority: Major
> Fix For: Impala 3.3.0
>
>
> IMPALA-5690 replaced thrift 0.9.0 with 0.9.3 in which THRIFT-3505 changed
> transport/TSSLSocket.py.
> In thrift 0.9.3, if the python version is lower than 2.7.9, TSSLSocket uses
> PROTOCOL_TLSv1 by default:
> {code:java}
> # For pythoon >= 2.7.9, use latest TLS that both client and server supports.
> # SSL 2.0 and 3.0 are disabled via ssl.OP_NO_SSLv2 and ssl.OP_NO_SSLv3.
> # For pythoon < 2.7.9, use TLS 1.0 since TLSv1_X nare OP_NO_SSLvX are
> unavailable.
> _default_protocol = ssl.PROTOCOL_SSLv23 if _has_ssl_context else
> ssl.PROTOCOL_TLSv1
> {code}
> And the SSL version should be passed as an argument to TSSLSocket.__init__
> instead of overriding self.SSL_VERSION in TSSLSocketWithWildcardSAN.__init__.
> The fix for IMPALA-5775 doesn't work against thrift 0.9.3. So if we use
> python lower than 2.7.9 (for example, it's python2.7.5 on Red Hat/CentOS 7.5)
> and set ssl_minimum_version to tlsv1.2, impala-shell command can't connect to
> impalad:
>
> {code:java}
> # impala-shell -i impalad01.example.com
> -k --ssl --ca_cert=/etc/cdep-ssl-conf/CA_STANDARD/truststore.pem
> SSL is enabled
> No handlers could be found for logger "thrift.transport.TSSLSocket"
> Error connecting: TTransportException, Could not connect to
> impalad01.example.com:21000: EOF occurred in violation of protocol
> (_ssl.c:579)
> {code}
>
