Hi,
I am using Root 5.22, and have the following Problem using an TEntryList with root:
This works:
ControlSample0->Draw(">>elist","Mu_N>=2","entrylist")
>85804
TEntryList * entrylist = elist
ControlSample0->SetEntryList(entrylist)
ControlSample0->Draw("Mu_N")
>85804
Now I switch on Proof:
TProof * p = new TProof("ebke@etpopt02:1093")
ControlSample0->SetProof()
ControlSample0->Draw("Mu_N")
>Looking up for exact location of files: OK (49 files)
>Looking up for exact location of files: OK (49 files)
>Validating files: OK (49 files)
>Warning in <TProofPlayerRemote::Finalize>: current TQueryResult object is undefined!
No plot was acutally printed. The worker logs are clean, the master Log shows this:
14:48:46 16962 Mst-0 | Info in <TXProofServ::SetQueryRunning>: starting query: 1
14:48:50 16962 Mst-0 | Info in <TPacketizerAdaptive::TPacketizerAdaptive>: no valid or non-empty file found: setting invalid
14:48:50 16962 Mst-0 | Error in <TProofPlayerRemote::InitPacketizer>: instantiated packetizer object 'TPacketizerAdaptive' is invalid
14:48:50 16962 Mst-0 | Error in <TProofPlayerRemote::Process>: cannot init the packetizer
Now, if I restart ROOT, and try generating the TEventList on Proof, it also does not work:
TProof * p = new TProof("ebke@etpopt02:1093")
tds = new TDSet(*ControlSample0)
tds->Draw(">>elist", "Mu_N>=2","entrylist")
>85804
entrylist = (TEntryList *) p->GetOutputList()->FindObject("elist")
tds->SetEntryList(entrylist)
tds->Draw("Mu_N")
>Looking up for exact location of files: OK (49 files)
>Files with entries to be processed: 0 (out of 49)
>Validating files: OK (49 files)
ControlSample0->SetEntryList(entrylist)
Error in <TChain::SetEntryList>: No list found for the trees in this chain
So both using the remote eventlist for remote processing and for local processing do not work.
One possible problem I could identify is that the eventlist generated locally has entrylist->GetLists()->At(0)->Print():
ControlSample0 /home/.../file.root
while the one generated by root has:
ControlSample0 file:///home/.../file.root
Do you have suggestions how to avoid or circumvent this problem?
Thanks,
Johannes
