私は単純な選択カウントクエリを作成しようとしました:
Properties props = new Properties();
props.setProperty("user", "someUser");
props.setProperty("password", "password1");
// Alternatively, you can use API key instead of user and password
// props.setProperty("apikey", "(your API key)")
// For using SSL connection (default is false)
props.setProperty("useSSL", "true");
// To run Hive jobs specify "type" parameter. The default is "presto"
props.setProperty("type", "presto");
java.sql.Connection conn = DriverManager.getConnection("jdbc:presto://api.treasuredata.com/sample_datasets", props);
Statement st = conn.createStatement();
try {
ResultSet rs = st.executeQuery("SELECT count(1) FROM www_access");
while (rs.next()) {
int count = rs.getInt(1);
System.out.println("result = " + count);
}
rs.close();
} finally {
st.close();
conn.close();
}
どうすればこのエラーを解決できますか:
HTTP protocol violation: Authentication challenge without WWW-Authenticate header
