Re: how to add a shareable node label?

Hi Frank, As far as I checked, all labels are "exclusive" in 2.7. In upcoming 2.8 release, we can get "non-exclusive" or sharable node labels. Thanks Sunil On Wed, Oct 5, 2016 at 8:40 AM Frank Luo wrote: > I am using Hadoop 2.7.3, when I run: > > $ yarn rmadmin

how to add a shareable node label?

I am using Hadoop 2.7.3, when I run: $ yarn rmadmin -addToClusterNodeLabels "Label1(exclusive=false)" I got an error as: … addToClusterNodeLabels: java.io.IOException: label name should only contains {0-9, a-z, A-Z, -, _} and should not started with {-,_} If I just use “Label1”, it will work

Re: native snappy library not available: this version of libhadoop was built without snappy support.

It seems to me this issue is the direct result of MAPREDUCE-6577 Since you’re on a CDH cluster, I would suggest you to move up to CDH5.7.2 or above where this bug is fixed. Best, Wei-Chiu Chuang > On Oct 4, 2016, at 1:26 PM, Wei-Chiu

Re: native snappy library not available: this version of libhadoop was built without snappy support.

Hi Uthayan, what’s the version of Hadoop you have? Hadoop 2.7.3 binary does not ship with snappy precompiled. If this is the version you have you may have to rebuild Hadoop yourself to include it. Wei-Chiu Chuang > On Oct 4, 2016, at 12:59 PM, Uthayan Suthakar >

I have set up a single node cluster (initially) and am attempting to write a file from a client outside the cluster. I’m using the Java org.apache.hadoop.fs.FileSystem interface to write the file. While the write call returns, the close call hangs for a very long time, eventually returns, but
