发帖数: 3979 | 1 I have text/csv files and want to upload them into Cloudera cluster, and use
them in Spark.
What's the best way to upload and convert text/csv file into PARQUET format?
Two load, use either file manager in Hue or SFTP?
To convert, I can think of 3 ways:
A.
In HIVE, create external table based on the original file,
then create new external table in PARQUET format ?
B.
In Spark, wse Scala code to convert ? Conversion speed might be a concern.

给的名字就是parquet,大概30厘米方块横竖交错。看着也不坏就是怪怪的，好像没人用
了八？而且，这个是不很
难换啊？难维护啊？是不是只有早期才用啊？不想为这个要投资太多啊
就是这样的： |

We introduced Cloudera Impala more than a year ago. It was a good launch for
us — it made our platform better in ways that mattered to our customers,
and it’s allowed us to win business that was previously unavailable because
earlier products simply couldn’t tackle interactive SQL workloads.
As a side effect, though, that launch ignited fierce competition among
vendors for SQL market share in the Apache Hadoop ecosystem, w... 阅读全帖 |

Dearest creature in creation
