> test_libhdfs_threaded_hdfspp_test_shim_static has started failing more often 
> and not a whole lot has changed that should directly impact this.
> It looks like the failure mode is error injection in the read pipeline.  
> Until HDFS-10951 is completed reads don't have a retry mechanism so any error 
> injection will cause that read to fail.  However that doesn't explain why 
> these failures have been happening more frequently lately.  The failures seem 
> to be hardware or timing specific; they almost never happen in some 
> environments and happen fairly frequently in others.  It might help to set up 
> a test harness to step through revisions and see if a specific commit causes 
> the probability of a failure to go up.
