----------------------------------
Summary: Hbase scan not returning all rows when setting heigher
value in scan.setCaching(cacheRow)
Key: HBASE-14508
URL: https://issues.apache.org/jira/browse/HBASE-14508
Project: HBase
Issue Type: Bug
Affects Versions: 1.0.0
Reporter: Lav Mudgal
Scan s = new Scan();
s.addFamily(Bytes.toBytes("cf1"));
s.setCaching(cacheRows);
s.setCacheBlocks(false);
s.setStartRow("30.0.2.2\01441756800\0");
s.setStopRow("30.0.2.3\01441756800\0");
ResultScanner scanner = table.getScanner(s);
long rows = 0;
try {
for (Result rr = scanner.next(); rr != null; rr = scanner.next()) {
rows++;
}
} finally {
scanner.close();
}
System.out.println("Total no of rows = " + rows);
When I run above code with cacheRows = 100 or 10000 it prints Total no of rows
= 480000
When I run above code with cacheRows = 100000 it prints Total no of rows = 10090
cacheRows <= 10083 prints 480000
cacheRows = 10084 prints 191595
cacheRows = 10085 prints 20169
cacheRows = 10086 prints 20170
cacheRows = 10087 prints 20171
cacheRows = 10088 prints 20172
cacheRows = 10089 prints 20173
cacheRows = 10090 prints 20174
cacheRows >= 10091 prints 10090
