Faisal Khan commented on HDFS-573: ---------------------------------- I ran unit tests on Ziliang's patch for libhdfs on Linux and here is the output http://pages.cs.wisc.edu/~faisal/libhdfs_testresult.txt . Tests look ok. > Porting libhdfs to Windows > -------------------------- > > Key: HDFS-573 > URL: https://issues.apache.org/jira/browse/HDFS-573 > Project: Hadoop HDFS > Issue Type: Improvement > Components: hdfs client > Environment: Windows, Visual Studio 2008 > Reporter: Ziliang Guo > Original Estimate: 336h > Remaining Estimate: 336h > > The current C code in libhdfs is written using C99 conventions and also uses > a few POSIX specific functions such as hcreate, hsearch, and pthread mutex > locks. To compile it using Visual Studio would require a conversion of the > code in hdfsJniHelper.c and hdfs.c to C89 and replacement/reimplementation of > the POSIX functions. The code also uses the stdint.h header, which is not > part of the original C89, but there exists what appears to be a BSD licensed > reimplementation written to be compatible with MSVC floating around. I have > already done the other necessary conversions, as well as created a simplistic > hash bucket for use with hcreate and hsearch and successfully built a DLL of > libhdfs. Further testing is needed to see if it is usable by other programs > to actually access hdfs, which will likely happen in the next few weeks as > the Condor Project continues with its file transfer work. > In the process, I've removed a few what I believe are extraneous consts and > also fixed an incorrect array initialization where someone was attempting to > initialize with something like this: JavaVMOption options[noArgs]; where > noArgs was being incremented in the code above. This was in the > hdfsJniHelper.c file, in the getJNIEnv function. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
