WangBo updated KUDU-2116:
-------------------------
Description:
I want to use kudu-client to fetch data.To improve efficiency,I use multi
thread to do this.Use KuduScanToken.intoScanner to get KuduScanner,then use
KuduScanner to fetch data.In single thread environment,it's ok.but when using
multi thread,every thread holds a kuduScanner to fetch data,exception occurs as
below:
