-------------------------------------
Summary: SpoolTooBigToDiskException when getting a huge resultset
Key: PHOENIX-1655
URL: https://issues.apache.org/jira/browse/PHOENIX-1655
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.2
Environment: HDP2.2
Reporter: Christophe S
I am working with timeseries and I would like to extract all the values for a
sensor (12M row for one year). I thought it would work with Phoenix as it would
stream the result but it seems it can't.
My table is as follows:
|M| VARCHAR |13|
|TS| TIMESTAMP |-|
|V| FLOAT |-|
|Q| CHAR |10|
|N| VARCHAR |10|
The code giving the exception:
{code}
final ResultSet rs = statement.executeQuery(
"select m, ts, v from MY_TABLE where m =
'mySensor'");
while (rs.next()) {
final String line = rs.getString(1) + "," +
rs.getDate(2).getTime() + "," + rs.getFloat(3);
ps.println(line);
}
{code}
After a while I got the following stacktrace:
{code}
Exception in thread "main" org.apache.phoenix.exception.PhoenixIOException:
