Missing rows while scanning table using java driver

[Priyanka Gugale]

Hi,

I am using Cassandra 2.2.0 and cassandra driver 2.1.8. I am trying to scan
a table as per suggestions given here
<http://www.myhowto.org/bigdata/2013/11/04/scanning-the-entire-cassandra-column-family-with-cql/>,
 On running the code to fetch records from table, it fetches different
number of records on each run. Some times it reads all records from table,
 and some times some records are missing. As I have observed there is no
fixed pattern for missing records.

I have tried to set consistency level to ALL while running select query
still I couldn't fetch all records. Is there any known issue? Or am I
suppose to do anything more than running simple "select" statement.

Code snippet to fetch data:

 SimpleStatement stmt = new SimpleStatement(query);
 stmt.setConsistencyLevel(ConsistencyLevel.ALL);
 ResultSet result = session.execute(stmt);
 if (!result.isExhausted()) {
   for (Row row : result) {
     process(row);
   }
 }
