Hi, I sometimes get this error when using the bulk loader with a xidmap:
I0112 01:34:53.476194 3138539 xidmap.go:282] Writing xid map to DB panic: Key cannot be empty goroutine 227 [running]: github.com/dgraph-io/dgraph/x.Panic(...) /ext-go/1/src/github.com/dgraph-io/dgraph/x/error.go:81 github.com/dgraph-io/dgraph/xidmap.(*XidMap).dbWriter(0xc0001ee620) /ext-go/1/src/github.com/dgraph-io/dgraph/xidmap/xidmap.go:186 +0x2bf created by github.com/dgraph-io/dgraph/xidmap.New /ext-go/1/src/github.com/dgraph-io/dgraph/xidmap/xidmap.go:104 +0x213 dgraph bulk -f -s --map_shards=2 --format=rdf --xidmap xidmap --http 3476.93s user 164.59s system 1657% cpu 3:39.66 total
My first assumption was that there was something wrong with the data files, but it doesn’t happen every time (even with the exact same data). I have been able to reproduce the error several times. It’s just that it’s not certain to happen every time.
If I restart but keep the previous xidmap it seems to never happen.
