RealignerTargetCreator problem with vcf file

Hi all!
I have a problem with this tool of GATK: RealignerTargetCreator. At the beginning I found this error:
FSLockWithShared$LockAcquisitionTask - WARNING: Unable to lock file /home/reference/Mills_and_1000G_gold_standard.indels.hg19.sites.vcf.idx because an IOException occurred with message: Funzione non implementata.
RMDTrackBuilder - Unable to write to /home/reference/Mills_and_1000G_gold_standard.indels.hg19.sites.vcf.idx for the index file, creating index in memory only

So I added this argument: --disable_auto_index_creation_and_locking_when_reading_rods
And I didn't find the same error. But now I have this problem:

I am using as reference hg 19. I downloaded the Mills vcf and index from
Thank you in advance,
