我正在通过Apache Phoenix中的PSQL(psql.py)加载批量数据的过程,但是由于某些原因使我抛出此错误:
const myFunction = (props) => {
const [count1, setCount1] = useState(0)
const [count2, setCount2] = useState(0)
const handleChange1 = ({ target: { value } }) => {
setCount1(value)
props.onCount1Change(value)
}
const handleChange2 = ({ target: { value } }) => {
setCount2(value)
props.onCount2Change(value)
}
useEffect(() => {
props.someRandomStuffs(count1, count2);
}, [])
return (
<div>
<input type="text" value={count1} onChange={handleChange1} />
<input type="text" value={count2} onChange={handleChange2} />
</div>
)
}
根据Phoenix教程https://phoenix.apache.org/Phoenix-in-15-minutes-or-less.html,我需要拥有3个文件; java.lang.IllegalArgumentException: Table "My_Table" not found
at org.apache.phoenix.util.SchemaUtil.generateColumnInfo(SchemaUtil.java:887)
at org.apache.phoenix.util.CSVCommonsLoader.buildColumnInfoList(CSVCommonsLoader.java:259)
at org.apache.phoenix.util.CSVCommonsLoader.upsert(CSVCommonsLoader.java:206)
at org.apache.phoenix.util.CSVCommonsLoader.upsert(CSVCommonsLoader.java:182)
at org.apache.phoenix.util.PhoenixRuntime.main(PhoenixRuntime.java:273)
my_table.sql
和my_table.csv
并启动以下命令:
my_table_queries.sql
这些文件的内容如下:
my_table.sql
./psql.py <your_zookeeper_quorum> my_table.sql my_table.csv my_table_queries.sql
my_table.csv
CREATE TABLE IF NOT EXISTS "some_namespace:my_table" (id BIGINT NOT NULL, username VARCHAR NOT NULL, CONSTRAINT my_pk PRIMARY KEY (id, username));
my_table_queries.sql
1,Martha
2,Scott
3,David
4,Alex
5,Vicky
当我通过sqlline.py访问Phoenix时,表在那里,但根本没有数据。我应该先创建表格还是以其他方式创建表格?
答案 0 :(得分:1)
在Phoenix中,表名称似乎区分大小写。由于创建表时已用双引号引起来,因此在运行批量装入作业时只需传递双引号即可。
my_table.sql
CREATE TABLE IF NOT EXISTS "MY_TABLE" (id BIGINT NOT NULL, username VARCHAR NOT NULL, CONSTRAINT my_pk PRIMARY KEY (id, username));
my_table_queries.sql:
SELECT id as "ID's", username as "User Name"
FROM "MY_TABLE"
GROUP BY id
ORDER BY count(username) DESC;
已被报告:https://issues.apache.org/jira/browse/PHOENIX-3541?attachmentSortBy=dateTime
的说明现在,如果要使用.csv文件将批量数据加载到HBASE中,可以尝试以下操作:http://dwgeek.com/apache-hbase-bulk-load-csv-examples.html/
