I'm running Ignite 1.5.0 Hadoop Accelerator version on top of CDH 5. I'm
trying to write my own SecondaryFileSystem, but as a first step, I created
one that just funnels all of the calls down to the
IgniteHadoopIgfsSecondaryFileSystem and I just log out every time one of my
methods is called. I'm using the default configuration provided in the
Hadoop Accelerator binary distribution except I added my secondary file
system to the configuration.
Every time I run hadoop fs -cat <filename> from the command line or
ignite.fileSystem("igfs").open(<filename>) from inside a java app, my log
statement in my SecondaryFileSystem's open method is printed out. Even if I
read the same file over and over. To me, that means my files aren't being
cached inside Ignite (which is the reason I'm looking into Ignite). I feel
like I must be missing something obvious. I tried creating a tiny (10 byte)
ASCII text file and reading that in case my files were too big in HDFS.
Thanks for any help.
