Hello,
I am using Hadoop on a small storage cluster (x86_64, CentOS 5.3,
Hadoop-0.19.1). The hdfs is mounted using fuse and everything seemed
to work just fine so far. However, I noticed that I cannot:
1) use svn to check out files on the mounted hdfs partition
2) request that stdout and stderr of Globus jobs is written to the
hdfs partition
In both cases I see following error message in /var/log/messages:
fuse_dfs: ERROR: could not connect open file fuse_dfs.c:1364
When I run fuse_dfs in debugging mode I get:
ERROR: cannot open an hdfs file in O_RDWR mode
unique: 169, error: -5 (Input/output error), outsize: 16
My question is if this is a general limitation of Hadoop or if this
operation is just not currently supported? I searched Google and JIRA
but could not find an answer.
Thanks,
Robert
