LzoThriftBlockInputFormat could not get correct start offset of column value

[packageyao]

I use this project for our lzo file indexing. Our lzo file use lzo thrift block format, I could create the index, but when I use the index to find the record in pig, I found that start offset is wrong, from this one I could not get the record, the correct start offset is less than current value. I read the code and found using LzoThriftBlockInputFormat could not get the correct start offset. Once I created my own index for another project, I use the SyncPoint of thrift block to point out the start offset. Can anyone give me some advice？
