Loading data inside Blazegraph can take quite a lot of time. Right now one of the ways to do it, in loadData.sh script, is to use SPARQL LOAD command. Unfortunately, it has timeout:
Processing wikidump-000000042.ttl.gz SPARQL-UPDATE: updateStr=LOAD <file:///srv/wdqs/munge//wikidump-000000042.ttl.gz> java.util.concurrent.TimeoutException at java.util.concurrent.FutureTask.get(FutureTask.java:205) at com.bigdata.rdf.sail.webapp.BigdataServlet.submitApiTask(BigdataServlet.java:292) at com.bigdata.rdf.sail.webapp.QueryServlet.doSparqlUpdate(QueryServlet.java:460)
which can break data loading, especially unattended process. We should either disable the timeout or make it much longer.
