--------------------------------------
Summary: add a flag to skip the libhdfs++ build
Key: HDFS-13362
URL: https://issues.apache.org/jira/browse/HDFS-13362
Project: Hadoop HDFS
Issue Type: Task
Reporter: James Clampffer
libhdfs++ has significantly increased build times for the native client on
trunk. This covers adding a flag that would let people build libhdfs without
all of libhdfs++ if they don't need it; it should be built by default to
maintain compatibility with as many environments as possible.
Some thoughts:
-The increase in compile time only impacts clean builds. Incremental rebuilds
aren't significantly more expensive than they used to be if the code hasn't
changed.
-Compile times for libhdfs++ can most likely be reduced but that's a longer
term project. boost::asio and tr1::optional are header-only libraries that are
heavily templated so every compilation unit that includes them has to do a lot
of parsing.
Is it common to do completely clean builds frequently for interactive users?
Are there opinions on what would be an acceptable compilation time?
