incompatible json format

[ram2012k]

The JSON input produced by HAMA fastgen is of the format
[srcid, 0 , [[sinkid1,edgevalue1],[sinkid2, edgevalue2]... ]]
**example ** [99,0,[[32,1995],[17,1809],[2,969],[50,1278],[25,321],[28,390]....]]

while the format required by LongTextJSONReader is of the form
​ [srcid,partitionid,srcvalue,[[sinkid1,edgeid1,edgevalue1],[sinkid2,edgeid2,edgevalue2]... ]]

what to do ?
