Hi,
The current Travis CI build is failing as seen from
https://travis-ci.org/apache/incubator-hawq?branch=master
Ed and I discussed about it, he found out that this might have happened due
to a recent protobuf update in brew. The last successful build had a
protobuf version of 3.2 and the latest(failing) is 3.4
Am working on setting up a local dev branch on my mac to test the failure
due to upgrade(till now I have been using centos).
>From the travis CI error message it looks like it is a problem with
namespace resolution while declaring stringstream and ostringstream
Error message -
/Users/travis/build/apache/incubator-hawq/depends/libyarn/src/libyarnclient/LibYarnClient.cpp:248:9:
error: unknown type name 'stringstream'; did you mean
'std::stringstream'?
stringstream ss;
^~~~~~~~~~~~
std::stringstream

/Users/travis/build/apache/incubator-hawq/depends/libyarn/src/libyarnclient/LibYarnClient.cpp:299:13:
error: unknown type name 'ostringstream'; did you mean

std::ostringstream

typedef basic_ostringstream<char> ostringstream;
Here are the possible solutions -
1 - To update travis.yml to use protobuf 3.2 only
2 - Use namespace while declaring stringstream or ostringstream
Also, trying to get to the root cause of the problem, if it is due to
protobuf upgrade, the only change that I see in protobuf regarding std
namespace is, in the recent version they moved it out of common/stubs.h -
https://github.com/google/protobuf/blob/master/CHANGES.txt#L61, not sure if
this is the problem but only thing I could find relative.
Will appreciate your input on this.
