Hi Rai, There are some excellent documents on the Apache NiFi site  to help you learn. There is an Administrator Guide , a User Guide , a Developer Guide , a NiFi In-Depth document , an Expression Language Guide  and processor and component documentation  as well. Currently, we are unaware of any official “book” resources.
Any corporate offerings are separate from the Apache project and should be investigated with said company.  https://nifi.apache.org/ <https://nifi.apache.org/>  https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html  https://nifi.apache.org/docs/nifi-docs/html/user-guide.html  https://nifi.apache.org/docs/nifi-docs/html/developer-guide.html  https://nifi.apache.org/docs/nifi-docs/html/nifi-in-depth.html  https://nifi.apache.org/docs/nifi-docs/html/expression-language-guide.html  https://nifi.apache.org/docs.html <https://nifi.apache.org/docs.html> Andy LoPresto alopre...@apache.org alopresto.apa...@gmail.com PGP Fingerprint: 70EC B3E5 98A6 5A3F D3C4 BACE 3C6E F65B 2F7D EF69 > On Oct 13, 2016, at 10:28 AM, Gop Krr <gop....@gmail.com> wrote: > > Hi All, > Is there any book for apache NiFi? > Also, does Hortonworks conducts training for NiFi? > Thanks > Rai
