Hi all, Some of our split BLAST jobs using the parallelism feature have been failing (apparently for a while, so this is not a recent problem from changes in the BLAST wrappers) as follows: <quote> The Galaxy framework encountered the following error while attempting to run the tool: Traceback (most recent call last): File "/mnt/galaxy/galaxy-dist/lib/galaxy/jobs/runners/tasks.py", line 141, in queue_job job_wrapper.finish( stdout, stderr, job_exit_code ) File "/mnt/galaxy/galaxy-dist/lib/galaxy/jobs/__init__.py", line 962, in finish if ( not self.external_output_metadata.external_metadata_set_successfully( dataset, self.sa_session ) and self.app.config.retry_metadata_internally ): File "/mnt/galaxy/galaxy-dist/lib/galaxy/datatypes/metadata.py", line 638, in external_metadata_set_successfully rval, rstring = simplejson.load( open( metadata_files.filename_results_code ) ) File "/mnt/galaxy/galaxy-dist/eggs/simplejson-2.1.1-py2.6-linux-x86_64-ucs4.egg/simplejson/__init__.py", line 328, in load use_decimal=use_decimal, **kw) File "/mnt/galaxy/galaxy-dist/eggs/simplejson-2.1.1-py2.6-linux-x86_64-ucs4.egg/simplejson/__init__.py", line 384, in loads return _default_decoder.decode(s) File "/mnt/galaxy/galaxy-dist/eggs/simplejson-2.1.1-py2.6-linux-x86_64-ucs4.egg/simplejson/decoder.py", line 402, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/mnt/galaxy/galaxy-dist/eggs/simplejson-2.1.1-py2.6-linux-x86_64-ucs4.egg/simplejson/decoder.py", line 420, in raw_decode raise JSONDecodeError("No JSON object could be decoded", s, idx) JSONDecodeError: No JSON object could be decoded: line 1 column 0 (char 0) Tool execution generated the following error message: Unable to finish job </quote> Reading the code, this is breaking after all the child jobs have finished, and the data has been merged, during the external set metadata step. This specific example was BLAST XML output, and the merge had produced a 4.2 GB file which ended mid record (evidently the output merge was not really successful). However, as a partial XML file, it would be invalid and might this cause problems with something in the metadata setting code - and explain the reported error? Peter
