Re: Solaris Port

Hi Colin, Exactly, as you noticed, the problem is the thread-local buffer needed to return from terror. Currently, terror just returns a static string from an array, this is fast, simple and error-proof. In order to use strerror_r inside terror, would require allocating a buffer inside terr

Re: Hadoop without HDFS

Yup, that's a great summary. More details... The HCFS wiki page will give you insight into some tests you can run to test your FileSystem plugin class, which you will put in a jar file described below. In general, hadoop apps are written to the file system interface which is loaded runtime, s

Hadoop without HDFS

Hi, I'm doing a research paper on Hadoop -- specifically relating to its dependency on HDFS. I need to determine if and how HDFS can be replaced. As I understand it, there are a number of organizations that have produced HDFS alternatives that support the Hadoop ecosystem, i.e. MapReduce, Hive, HB

Re: Solaris Port

Hi Colin, Thanks for the hints around JIRAs. You are correct errno still exists, however sys_errlist does not. Hadoop uses a function terror (defined in exception.c) which indexes sys_errlist by errno to return the error message from the array. This function is called 26 times in various plac

Re: Solaris Port

Hi Malcolm, In general we file JIRAs for particular issues. So if one issue is handling errlist on Solaris, that might be one JIRA. Another issue might be handling socket write timeouts on Solaris. And so on. Most of these should probably be HADOOP tickets since they sound like they are mostly
